Abstract
This application relates to biological pharmacy and biochemical engineering, and more particularly to a method of preparing a (S)-1-benzyl-1,2,3,4,5,6,7,8-octahydroisoquinoline compound. This method includes: subjecting a 1-benzyl-1,2,3,4,5,6,7,8-octahydroisoquinoline raceme as a substrate to selective oxidation in the presence of a monoamine oxidase and the non-selective reduction to prepare the (S)-1-benzyl-1,2,3,4,5,6,7,8-octahydroisoquinoline compound, where the monoamine oxidase has an amino acid sequence as shown in SEQ ID NO: 1 or an amino acid sequence having an identity of more than 80% with SEQ ID NO: 1. The kinetic resolution is carried out in the presence of the monoamine oxidase as a catalyst and a reductant, and the resulting product has a high chiral purity.
