Epothilone A, epothilone B, analogs of epothilone and libraries of epothilone analogs are synthesized. Epothilone A and B are known anticancers agents that derive their anticancer activity by the prevention of mitosis through the induction and stabilization of microtubulin assembly. The analogs of epothilone are novel. Several of the analogs are demonstrated to have a superior cytotoxic activity as compared to epothilone A or epothilone B as demonstrated by their enhanced ability to induce the polymerization and stabilization of microtubules.

The total synthesis of taxol employs a convergent synthetic plan. The synthetic plan may also be employed to produce a large number of taxol analogs. Taxol analogs having skeletal extensions are inaccessible by modification of the natural product but are readily produced by employing the convergent synthetic plan herein.
