Kinetic resolution of cyclic β-hydroxy sulfides has been achieved by reaction with benzoyl chloride in the presence of a catalytic amount (0.1 mol %) of a chiral 1,2-diamine combined with triethylamine. This reaction affords the corresponding benzoates and unreacted alcohols with excellent enantioselectivities.
