Bisesters of cinchonine, cinchonidine, dihydrocinchonine and dihydrocinchonidine with terephthalic acid and isophthalic acid are used as chiral auxiliaries for osmium tetroxide-catalyzed asymmetric dihydroxylation of olefins such as styrene, a-methylstyrene, methyl cinnamate, ethyl cinnamate, isopropyl cinnamate, cinnamyl alcohol, cyclohexene, 1-methylcyclohexene, 1-phenylcyclohexene, cycloheptene, cyclooctene, 3-chloro-1-propene, 1-hexene and methyl fumarate, and the enantiomeric excess in every case has been determined.
