CHEMOENZYMATIC SYNTHESIS

Bridging science and Industrial applications

Overview

In chemoenzymatic synthesis biocatalytic methods and contemporary organic methods are synergistically combined towards a multistep or one-pot process. This strategy allows to benefit of the exceptional regio- and stereo-selectivity of enzymatic transformations, while also taking advantage of the variety of organic reactions to create chemical bonds which are unattainable using purely enzymatic or organic means. Therefore, chemoenzymatic strategies hold enormous potential for accessing valuable building blocks, natural products and bioactive molecules. Moreover, particularly chemoenzymatic one-pot processes represent an attractive synthetic concept for the improvement of overall process efficiency by decreasing the required number of work up and purification steps. Due to avoidance of such time-, capacity- and solvent-intensive process steps, one-pot syntheses contribute to a significantly improved process economy as well as to more sustainable procedure.

Making reactions compatible

A key criterion for chemoenzymatic processes is the compatibility of the individual reaction steps with each other. Accordingly, most of today’s known processes are based on either chemocatalytic multi-step reactions or pure biotechnological processes, while our group is focusing on the fusion of both fields. Thus, in our research, various strategies for the combination of chemo- and biocatalysts towards the development of chemoenzymatic processes are studied. Therein we could demonstrate that enzymatic reactions can be combined with metal-catalyzed as well as organocatalyzed reactions. In the past years we could sucessfully develope processes combining these types of catalysts (10.1002/anie.201409590 and 10.1021/acscatal.8b05062).
