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.
