Technology Highlights

Asymchem promotes the application of flow reaction through modular technology

Asymchem built a flexible and practical modular technology platform for flow reaction that can be used in large-scale production with hundreds of small-scale, pilot-scale, and commercial-scale equipment platforms. Through the modular combination, automated precise control, rapid construction of reactors, screening of reaction conditions, and implementation of projects, Asymchem can meet the client’s demand for a continuous flow drug production. Asymchem has achieved the ton-level manufacturing of both key intermediates and APIs for several innovative drugs through the proficient application of flow reaction technology. This makes Asymchem one of the very few companies in the world that has extended the use of such technology to manufacturing.

Asymchem has always focused on the R&D and commercialization of green pharmaceutical technology. After a long period of cultivation and accumulation, we have not only reached the large-scale application of flow reaction technology in the production of innovative drugs, but also achieved the efficient application of the flow equipment for post-reaction treatment, wastewater treatment, etc. Currently, more than 30% of the scaled-up production for clinical mid-late stage projects have successfully implemented flow reaction and other green pharmaceutical technologies.

Asymchem’s co-authors Org. Process Res. Dev. (OPRD) | “Development and Execution of the Production-Scale Flow [2+2] Photocycloaddition”

Recently, Asymchem (stock code: 002821.SZ) co-authored a paper with Amgen Inc.-“Development and Execution of a Production-Scale Continuous [2+2] Photocycloaddition” in the academic journal of American Chemical Society (ACS) called Org. Process Res. Dev. (OPRD). This was a breakthrough in scaling up photochemical applications and was a result of a collaboration between Amgen’s Process Development Group and Asymchem’s Center for Process Sciences (CEPS). Together, we overcame the long-standing scale limitation of the traditional [2+2] cycloaddition reaction by establishing a multi-kilogram scale production system and has become a global pioneer in industry manufacturing using [2+2] photocycloaddition reaction.

Asymchem’s patent granted – “Flow synthesis-Purification device and flow reaction system

Asymchem’s “Flow Synthesis-Purification Integrated Unit and Flow Reaction System Containing it” has been granted a national patent for invention (CN210683637U). This utility model does not only improve the conversion rate of raw materials and product yield, but also increases product purity, shorten the reaction route, reduce the equipment quantity, reaction time, floor space, labor intensity and energy consumption, etc.

Asymchem’s patent granted – “Flow synthetic route of 2-chloropyrimidine-4-carboxylic acid compounds”

Asymchem’s patent “Flow synthetic route of 2-chloropyrimidine-4-carboxylic acid compounds” was granted by the National IP Administration (No. CN110642789B). It provides a continuous synthetic solution by carrying out a continuous methylation reaction with certain methyl Grignard reagent and then undergo flow oxidation producing the final target compound with a total yield of 70%. Therefore, it effectively addressed issues like high cost, low product yield, high environmental pollution in the existing preparation of 2-chloropyrimidine-4-carboxylic acid compounds, which greatly improved the reaction efficiency. The cost for product synthesis and the safety risks associated with the use of methyl Grignard reagents are beneficial for the industrial scale-up manufacturing.

Asymchem’s patent granted – “Preparation of trifluoroalkyl sulfone compounds”

Asymchem’s patent “Preparation of trifluoroalkyl sulfone compounds” was granted by the National IP Administration (No. CN110683999B). This method uses hydrogen peroxide for the continuous oxidation of trifluoroalkyl sulfide to obtain a product system containing trifluoroalkyl sulfone compounds. This invention uses a continuous feed, which improves the material contacting effect and reduces the pressure tolerance requirement for flow reactors.

Asymchem’s patent granted – “Synthetic route of fluorinated chiral amine compounds”

Asymchem’s patent “Synthetic route of fluorinated chiral amine compounds” was granted by the National IP Administration (No. CN110950788B). The route comprises an amino donor reacting with certain fluorinated dihydroxy ketal compound, catalyzed by a transaminase to produce chiral fluorinated amines, wherein the transaminase is derived from multiple strains. Such transaminase has substrate specificity and catalytic activity for a variety of fluorinated dihydroxy ketals. This patented route not only accounts for less steps, higher product yields and significantly lower production costs, but also effectively reduces the use of organic solvents and waste generation.

Asymchem’s patent granted – “Synthetic route for chiral diamine compounds”

Asymchem’s patent “Synthetic route for chiral diamine compounds” was granted by the National IP Administration (CN110982856B). Chiral diamine compounds are widely found in many biologically active natural products and drug molecules, being a research hotspot for chemists. The conventional synthetic route would use highly toxic azide compounds or cyanogenic reagents, with a large amount of wastes, which are difficult to be disposed of. The new synthetic route provided by this invention involves the biocatalytic reaction of aminotransferase, which is derived from multiple strains and has high substrate selectivity and activity. Using this bioenzyme-catalyzed synthesis of chiral diamine compounds expands the range of substrate applicability and shortens the overall route, resulting in high product yields, low production costs, and less organic solvent uses and wastes.
