Article abstract of DOI:10.3987/COM-97-7892

Dihydroxyalkanoic ester derivatives (4a,b) and (5a,b) of 20S-camptothecin (1) were diastereoselectively synthesized by exploiting osmium-catalyzed asymmetric dihydroxylation based on the Sharpless procedure. The absolute configuration of the newly formed
