Abstract: The asymmetric dihydroxylation of ortho-substituted 1,2-diphenylethenes affords the corresponding diols in good yields (77~89%) and high enantiomeric excesses (73~98%) in the presence of catalytic amount OsO4 and four different chiral ligands respectively.

Key words: asymmetric dihydroxylation, chiral diol
