  摘要：

  An isosteric C-glycoside phosphono analogue of dec-9-enyl beta -D-galactopyranosyl-(1 -->4)-alpha -D-mannopyranosyl phosphate was synthesised and showed high biological activity in the Leishmania MPT assay. A one-step Horner-Emmons/Michael reaction was developed for the stereoselective preparation of cc-D-mannosyl methanephosphonate derivatives. (C) 2001 Elsevier Science Ltd. All rights reserved.

  A set of isosteric phosphono (C-glycoside) analogues of Leishmania lipophosphoglycan fragments have been synthesised by making use of a sequence of uniformly stereoselective glycosylation reactions of phosphono-oligosaccharide glycosyl acceptors with phosphono-oligosaccharide thioglycosides.
