title: Synthesis of glycosides of alpha-D-mannopyranose 6-(alpha-D-glucopyranosyl phosphate). The putative ligatin receptor.
abstract: p-Nitrophenyl alpha-D-mannopyranoside 6-(alpha-D-glucopyranosyl phosphate) (7) and 6-(alpha-D-galactopyranosyl phosphate) (8) were synthesized by condensation of the appropriate peracetylated glycosyl phosphate with p-nitrophenyl 2,3,4-tri-O-benzoyl-alpha-D-mannopyranoside followed by alkaline deprotection. 1H-, 31P-, and 13C-n.m.r. spectroscopy were used to establish the structures of 7 and 8, and to examine the conformational preferences about the phosphoric diester linkage.
