STEREOSELECTIVE β-D-PSICOFURANOSYLATION AND SYNTHESIS OF β-D-PSICOFURANOSYLCERAMIDE

摘要

Psicofuranosylations of alcohols and phenol 3a-e with benzyl D-psicosyl phthalate 2 occurred on the β-face to give β-D-psicoside 4a-e in excellent yields. The reaction of ceramide 5 with 2 and deprotections of acetonide and three benzoates of the resulting glycoside afforded β-D-psicosylceramide 1.
