Synthesis of taxoids II. Synthesis and antitumor activity of water-soluble taxoids
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.
