A totalsynthesis of the potent, naturally occurring immunomodulators (−)-rapamycin (1) and (−)-27-demethoxyrapamycin (2) has been achieved via a unified, highly convergent synthetic strategy. Both targets were elaborated from common building blocks A−E, the latter available in decagram quantities. Herein we present the construction of the ABC northern perimeters of 1 and 2.

rubiginone A2, C2 and fujianmycin A are described. The synthesis involves Diels–Alder/aromatization and photo chemical reactions as keysteps to construct the tetracyclic frame of benz[a]anthraquinone skeleton. Sharpless epoxidation, a copper-catalyzed regioselective epoxide opening, and enynemetathesisreactions are utilized as the keysteps for the synthesis of chiral vinylcyclohexene.
