Abstract
AbstractWe describe herein the asymmetric total synthesis of sphingofungin E, which has potent immunosuppressive activity. Key steps include asymmetric desymmetrization by bromolactonization, stereocontrolled construction of four contiguous stereogenic centers through allylic C–H oxidation and epoxide ring opening, regioselective elongation of a dialdehyde, and Hofmann rearrangement by using PhI(OCOCF3)2.
