Abstract

An effective kinetic resolution of hydroxymethylchromanes racemic 2a and 3a has been achieved by means of enantioselective transesterification with vinyl acetate in organic solvents. The alcohols (-)-R-2a and (-)-S-3a were obtained with high optical purities (94 and 98% ee) in 70% and 38% yields, respectively. The influence of the enzyme source and the character of the solvent on the enantioselectivity were studied.
