Double asymmetric dihydroxylation of (E)-alpha,beta-unsaturated ester(2) with a catalytic amount of potassium osmate and chiral ligand gave dihydroxy compounds (3a and 4a) selectively. Polyhydroxylated pyrrolidines (10 and 14) were synthesized from corresponding methoxymethy ether (3c) and tert-butyl-dimethylsilyl ether(4d), respectively.
