A synthetic pathway for the synthesis of unit-B of cryptophycin-24 has been developed using Sharpless asymmetric dihydroxylation as the key step. This study shows that direct azidation of α-hydroxy acid ester using diphenylphosphoryl azide is beneficial to asymmetric synthesis of α-amino acid without the loss of chirality during the transformation.
Catalytic asymmetric dihydroxylation of olefins with recyclable osmate-exchanged chloroapatite catalyst

An osmate-exchanged chloroapatite (CAP-OsO4) catalyst was prepared by an ion-exchange technique. CAP-OsO4 efficiently catalyses asymmetric dihydroxylation of olefins including α,β-unsaturated esters and amides to afford the corresponding diols in high yields and enantioselectivities. The catalyst was reused for several cycles with consistent activity.

Synthesis of novel taxoid water-soluble prodrugs that have 2′-substituted amino acid derivatives with spacer is described. Enantioselective synthesis of the C-13 side chains proceeded through the asymmetric dihydroxylation. Several compounds had good solubility in saline and showed potent antitumor activity against B16 melanoma in mice.
