A program directed toward a total synthesis of 1-deoxypaclitaxel is described. The most direct route consists of six steps from the previously described diketone 12 and proceeds in 18% overall yield. The transformations involved in reaching the target molecule 22 consist of stereoselective α-ketol generation, an EtAlCl2-catalyzed transannularhydrideshift, regioselective monomesylation, and a Wagner−Meerwein
