A practical chemo-enzymatic approach to highly enantio-enriched cyanohydrin acetates
摘要:
The preparation of enantiopure cyanohydrin acetates via enzymatic hydrolysis has been investigated by screening a range of biocatalysts and reaction conditions. Enzymatic resolution has been optimised through variation of the hydrolase biocatalyst and reaction conditions leading to synthetically useful routes to enantiopure cyanohydrin acetates.

Enzymatickineticresolution of a series of aromatic and aliphatic cyanohydrins in organic media has been investigated. The behavior of potential lipases, molecular sieves, acyl reagent, reaction temperature, and organic solvents on the kineticresolution was studied. The influence of substrate structure, steric, and electronic nature and position of the aryl substituent on the enantioselectivity was
