communis) have been applied to catalyze the asymmetricsynthesis of (R)‐4‐methylsulfanylmandelonitrile, a key building block of thiamphenicol and florfenicol. Here, four hydroxynitrile lyase (HNL) isozymes from Badamu were cloned and heterologously expressed in Pichia pastoris. The biochemical properties and catalytic performances of these isozymes were comprehensively explored to evaluate their efficiency

Acyloins are prepared in high yields reaction between Grignard reagents and -trimethylsilyl ethers of aldehyde cyanohydrins: the method is particularly useful for the preparation of discrete acyloins in which the substituents are unsymmetrically disposed about the α-hydroxyketone moiety.

A series of cyanohydrinacetates (1)–(47) of widely varying structures, potential chiral building blocks for numerous synthetic applications, has been prepared in good chemical and often high optical yields by enzymatic hydrolysis of their racemic acetates in the presence of an ester hydrolase from Pseudomonas sp.
