摘要：

7-O-Triflates of baccatin III or of taxol analogs are convenient precursors in alternate syntheses of Delta(6,7)-taxols and 7 beta,8 beta-methano (cyclopropyl) taxols, two of the products initially obtained from reaction of taxols with methylDAST; hydrazine is an effective reagent for conversion of the 10-acetate group to the hydroxyl group.
