Structure determination and synthesis of a new cerebroside isolated from the traditional Chinese medicine Typhonium giganteum Engl.
摘要:
A new cerebroside with C18-4,8-sphingadienine as the long chain base has been isolated from the traditional Chinese medicine Typhonium giganteum Enal., and its structure was determined by 2D NMR and MS methods. It was then synthesized using D-xylose and ascorbic acid as the chiral starting materials. (C) 2002 Elsevier Science Ltd. All rights reserved.

The first total synthesis of a novel alpha-galactoglycosphingolipid clarhamnoside has been achieved through a straightforward strategy. A thiogalactosyl donor with a benzylidene group at C-4 and C-6 and nonparticipating p-methoxybenzyl group at C-2 was successfully employed in the stereocontrolled syntheses of alpha-GalGSLs. The N-Phth-protected trifluoroacetimidate donor for terminal disaccharide
