cyanohydrins. Among them, the cyanosilylation of carbonylcompounds using trimethylsilyl cyanide (TMSCN) is widely utilized for the synthesis of cyanohydrins. Several reagents including Lewis acids, Lewis bases, metal alkoxides, bifunctional catalysts, iodine and inorganic salts have been found to effectively transfer the cyano group from TMSCN to carbonylcompounds. Various types of Lewis acids such as AlCl3

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.
