Deliverables
This task will focus on enabling resolution through the crystallization behaviour. Chiral compounds can possess complex solid state, thermodynamic and crystallization behaviour. Pharmaceuticals have the tendency to form several competing solid forms, which may or may not enable chiral resolution. The crystallization of industrial chiral compounds takes place in complex multicomponent mixtures in which next to the enantiomers and solvent also other compounds (resolving agents, impurities, additives, anti-solvents) are influencing the process. Additionally, In hybrid reaction processes an additional complexity is the racemizing agent impacting on the phase diagram and crystallization behaviour. ESR13 will develop a screening tool quickly and reliably determine the crystallization-based resolution possibilities of a new chiral compound in multicomponent solutions.
Scientific article of ESR2 on Methods and Design Rules developed for Continuous Configurations of Crystallization-based Chiral SynthesisDevelopment of Continuous Crystallization-enabled Chiral Synthesis Processes. This part will be led by JtH at USTRATH with the involvement of ESR2 at USTRATH (experiments) and ESR4 at ETH (process modelling). There is a strong connection with ESR5 at RUN and ESR6 at SYNCOM working on batchwise crystallization-enabled chiral synthesis. Recently, it was shown that a combination of an aselective reversible reaction with Viedma Ripening leads to a chiral synthesis route [8]. ESR2 will transfer this new batchwise chiral synthesis route into continuous configurations. The partner SYNCOM is willing, during the industrial secondment, to facilitate the synthesis of substantial amount of raw material needed to perform long term continuous experiments.
Scientific article of ESR8 on optimization methods for Viedma RipeningViedma Ripening is a potential examples of Hybrid Resolution. ESR8 will optimize crystallization-based hybrid resolution techniques such as Viedma Ripening.
Scientific article of ESR1 on Design Rules for Batch and Continuous ResolutionThis part will be led by ASM of OVGU with the involvement of ESR1 at OVGU and ESR4 at ETH. Substantial knowledge was acquired in the last decades in designing, optimizing and realizing large scale continuous processes, in particular in petro-chemistry for the production of (non-crystalline) bulk chemicals. Often a direct connection of a large number of reaction and separation steps could be successfully applied. To allow for such direct coupling and to avoid undesired buffer steps, the intrinsic time constants of the relevant sub-steps have to be identified and quantified. Building on this key information, a well-established theoretical framework is available striving to match the residence times of the components in all steps by identifying and establishing suitable operating conditions including a selection of the specific unit types and sizes. Hereby, the theoretical framework developed compares the characteristic times required by each relevant individual process step with the times provided in this step as characteristic residence times. Typically Damköhler-numbers are applied to facilitate and generalize the analysis. ESR1 will provide the framework for the design of batch and continuous crystallization processes based on dimensionless numbers.
Scientific article of ESR14 on the developed Process Analytical Tools based on chiroptical spectroscopyDespite the importance of chirally pure crystalline products, there is no Process Analytical Tool (PAT) that can monitor the enantiomeric excess in the crystalline phase of a suspension during a resolution process. However, PAT are of key importance, particularly in the move towards continuous manufacturing as they will enable appropriate control of the processes, but also in batch processes relying on decracemization where detecting the endpoint can be achieved. ESR14 will develop a tool based on chiroptical spectroscopy and Second Harmonic Generation.
Scientific article of ESR7 on optimization methods for SOATESR7 will optimize crystallization-based hybrid resolution techniques such as SOAT (Second Order Asymmetric Transformation). This task will develop crystallization-based hybrid resolution processes allowing high enantiomeric yields.
ESR presentation on tool during final conferenceThe ESRs will present their findings during the dedicated network events in short, focussed presentations
Scientific article of ESR15 on the Process Analysis Tools based on classical techniques with automated sampling.Despite the importance of chirally pure crystalline products, there is no Process Analytical Tool (PAT) that can monitor the enantiomeric excess in the crystalline phase of a suspension during a resolution process. However, PAT are of key importance, particularly in the move towards continuous manufacturing as they will enable appropriate control of the processes, but also in batch processes relying on decracemization where detecting the endpoint can be achieved. ESR15 will enable such a tool using classical techniques with automated sampling.
Scientific article of ESR10 on methods to predict multicomponent conglomerate systems of chiral compoundsOnly 5-10% of the chiral compounds form conglomerates while crystallization-based resolution techniques often rely on the discovery of a conglomerate forming system. This project will establish the formation principles of conglomerate co-crystals, salts, solvates and other solids using experimental screening as well as database mining and molecular simulation techniques. These formation principles will enable changing the solid state of a chiral compound from racemic compound to multicomponent conglomerate and thus open up the route towards resolution. This would lead to a 10-fold increase in the application of chiral resolution through preferential crystallization. ESR10 will develop crystal engineering approaches
Scientific article of ESR5 on new Routes for Viedma Ripening-based Chiral SynthesisChemists often find a way to produce some enantiomeric enrichment through synthesis, but usually do not reach the required purity directly. We have recently reported that the combination of a reaction, crystallisation and the process of Viedma ripening can lead to an enantiopure crystalline product. ESR5 will extend on this very promising combination identifying new opportunities for chiral synthesis based on reversible chemical reactions to racemize compounds.
Scientific article of ESR3 on Methods and Design Rules developed for Continuous Preferential Crystallization TechniquesThis part will be led by MM at ETH with the involvement of ESR3 at OVGU and ESR4 at ETH. Both ESRs will have an approach that combines process modelling and experiments. Single enantiomeric crystals can be produced in different ways. If sufficient enrichment in the target enantiomer can be achieved by an upstream asymmetric synthesis step or by an ancillary technique, e.g. chiral chromatography, then a rather conventional cooling or antisolvent crystallization can be carried out. These processes exist both in the batch and in the continuous mode, which exhibit however different performance. Alternatively, there are at least two techniques, namely preferential crystallization and Viedma ripening, that allow forming single enantiomeric crystals starting from a racemic mixture (50/50 of the two enantiomers) using a very small amount of seeds of the target enantiomer. These processes have so far been operated in a batch mode, and making them continuous is a challenge. This task will deliver tools to design Crystallization-enabled Continuous Resolution Processes.
Scientific article of ESR4 on Methods and Design Rules developed for Continuous Viedma Ripening and on Process models for Crystallization-based Continuous ResolutionESR4 will construct process models of continuous crystallization processes to be used for optimization and control, in relation to ESR1. Additionally, a process model will be developed that will aid the optimization and control of crystallization-enabled chiral synthesis in relation to ESR2. ESR4 will deliver process models for Crystallization-enabled Continuous Resolution Processes.
Scientific article of ESR11 on methods to change the solid state of a chiral compound to enable crystallization-based resolutionOnly 5-10% of the chiral compounds form conglomerates while crystallization-based resolution techniques often rely on the discovery of a conglomerate forming system. This project will establish the formation principles of conglomerate co-crystals, salts, solvates and other solids using experimental screening as well as database mining and molecular simulation techniques. These formation principles will enable changing the solid state of a chiral compound from racemic compound to multicomponent conglomerate and thus open up the route towards resolution. This would lead to a 10-fold increase in the application of chiral resolution through preferential crystallization. ESR11 will develop high throughput pre-screening methods through in line detection of non centro-symmetric crystals –including efflorescent solvates.
Scientific article of ESR6 on new racemization routes and optimized deracemization processes using designed transition metal catalystsMany chiral pharmaceuticals owe their chirality to the presence of secondary alcohol or amine functionalities for which the hydrogen attached to the chiral centre is not readily removed with bases. ESR6 will enable racemization by applying designed transition metal catalysts and optimize deracemization processes using these catalysts. This task will extend the range of compounds that can be produced by developing new opportunities for Viedma ripening-enabled and SOAT-enabled chiral synthesis routes. ESR6 will enable racemization by applying designed transition metal catalysts (D4.2). In addition to the racemization catalysts, the main factors influencing racemization rate (e.g. temperature, pH value, presence of additives, nature of solvent, presence of a solid product phase) will be identified.
Scientific article of ESR9 on new racemization methods using organocatalysts and enzymes.Racemization is key in many deracemization strategies. As not all chiral compounds of interest can be racemized directly or fast enough, it is in many cases possible to overcome this limitation: we reported in 2009, that conglomerate deracemization of chiral organic compounds is possible, employing racemization that occurs via the reverse steps of reversible asymmetric organic reactions and with achiral or racemic catalysts. Racemization of chiral products in solution or at the crystal/solution interface will thus be achieved via (i) the reverse reaction step or (ii) direct racemization, e.g. in the α-position of CH-acidic compounds, both catalyzed by achiral (or racemic), environmentally friendly and cheap organocatalysts, highly active transition metal catalysts or by enzymes (e.g. racemase, epimerase). ESR9 will focus on the development of racemic and achiral catalysts for stereoselective reactions yielding chiral bioactive organic compounds or valuable building blocks of pharmaceuticals and which can be racemized either in solution or at the crystal/solution interface. This task will extend the range of available racemization reactions to enable Hybrid Resolution.
ESR presentation on tool during workshop 2 / conferenceThe ESRs will present their findings during the dedicated network events in short, focussed presentations
Scientific article of ESR12 on the tool to determine competing solid state behaviour in multicomponent chiral systemsThis task will focus on enabling resolution through the crystallization behaviour. Chiral compounds can possess complex solid state, thermodynamic and crystallization behaviour. Pharmaceuticals have the tendency to form several competing solid forms, which may or may not enable chiral resolution. The crystallization of industrial chiral compounds takes place in complex multicomponent mixtures in which next to the enantiomers and solvent also other compounds (resolving agents, impurities, additives, anti-solvents) are influencing the process. Additionally, In hybrid reaction processes an additional complexity is the racemizing agent impacting on the phase diagram and crystallization behaviour. ESR12 will develop a screening tool for complex solid state and thermodynamic behaviour of chiral compounds in multicomponent solutions.
