摘要：

New protocols for the selective protection of the C(7) and C(10) hydroxyl groups of 10-deacetyl baccatin III are described, leading to more efficient semisyntheses of taxol and taxol analogs. The C(10) hydroxyl group of 10-DAB can be highly selectively acylated or silylated, and subsequent selective protection of the C(7) hydroxyl group then becomes straightforward.
