A method for the formation of Taxol's ABC ring system has been developed. General methods for the synthesis of versatile synthons for Taxol's A ring (8) and C ring (55) are presented. A model study using a simplified C ring synthon (17) confirmed the viability of the sequential Shapiro—McMurry strategy for formation of Taxol's B ring. Careful exploration of the chemistry of various A—B ring conjugates allowed the development of a successful method for formation of the B ring in a more functionalized system.
