A novel approach is proposed to prepare a set of immobilized derivatives of a enzyme covalently rigidified through different regions of its surface. Six different variants of penicillin G acylase (PGA) from Escherichia coli (which lacks Cys) were prepared

Paragraph 0096-0099; 0120-0123, (2020/08/09)
The invention discloses a synthesis method of a (S)-2-aryl propionate compound. The (S)-2-aryl propionate compound shown in the formula IV is obtained by taking a compound shown in a formula I and a compound shown in a formula II as raw materials and reacting under the conditions of a chiral ligand shown in a formula III, a nickel catalyst, a photocatalyst, a reducing agent and alkali under the condition of visible light. The method has the advantages of cheap and easily available raw materials, convenient generation, mild conditions, environmental protection and safety, the photocatalyst canbe recycled, the production cost is greatly reduced, the test operation is simple, less waste is generated, and the method can be developed into an industrial production method.

The esterification of 2-phenylpropionic acid was investigated as a model system for enzyme catalysed (CALB, Novozyme 435) reactions in bio-based solvents. A multi-parameter correlation taking into account solvent parameters was developed to explain experimental observations. A continuous flow process using p-cymene as the solvent was operated over several weeks, thus combining a sustainable solvent and flow chemistry for kinetic resolution.
