✦ Synopsis

Catalytic asymmetric acylation of meso-l,2-ciols has been successfully performed by the reaction with benzoyl chlarid~ in the presence of 0.5 mol% of ¢hiral ~amine derived from (S)-proline combined with a stoichiom etric amount of triethylamine to give the corresponding monobenzoate with good to excellent enantioselecti vities.
