Abstract :

This study aimed to optimize the kinetic resolution of building blocks for the synthesis of beta-blockers using Candida rugosa lipases, which could be potentially used to synthesize enantiomerically pure beta-blockers further. Reaction mixtures were incubated in a thermostated shaker. Qualitative and quantitative analyses of the reaction mixtures were performed using chiral stationary phases and the UPLC-IT-TOF system. Of the 24 catalytic systems prepared, a system containing lipase from Candida rugosa MY, [EMIM][BF(4)] and toluene as a two-phase reaction medium and isopropenyl acetate as an acetylating agent was optimal. This resulted in a product with high enantiomeric purity produced via biotransformation, whose enantioselectivity was E = 67.5. Using lipases from Candida rugosa enables the enantioselective biotransformation of the beta-blockers building block. The biocatalyst used, the reaction environment, and the acetylating agent significantly influence the efficiency of performer kinetic resolutions. The studies made it possible to select an optimum system, a prerequisite for obtaining a product of high enantiomeric purity. As a result of the performed biotransformation, the (S)-enantiomer of the beta-blocker derivative was obtained, which can be used to further synthesize enantiomerically pure beta-blockers.
