A series of 26-substituted epothilones B (3, 22, 23a–n and 24a–h,j–l,o) have been constructed by total synthesis involving a selective Wittig olefination, an aldol reaction and a macrolactonization as key steps.

The chemical synthesis of a series of 26-substituted epothilones B is described. Fully protected 26-hydroxydesoxy-epothilone B (7), prepared via the macrolactonization strategy, served as a common precursor to the designed epothilones described. The synthesized compounds were members of a large epothilone library whose biological screening led to the identification of a number of highly potent antitumor
