Abstract
[reaction: see text] Total synthesis of sphingofungin E (1) is described. Overman rearrangement of an allylic trichloroacetimidate derived from diacetone-D-glucose generated tetra-substituted carbon with nitrogen, and subsequent Wittig olefination afforded the highly functionalized part in sphingofungin E (4) stereoselectively. Coupling reaction of 4 with the C(12) hydrophobic part, followed by further manipulation, completed the total synthesis.
