Abstract
Abstract The reaction of p-nitrophenyl 2,3-O-isopropylidene-α- d -mannopyranoside and 2-methyl-(3,4,6-tri-O-acetyl-1,2-dideoxy-α- d -glucopyrano)-[2,1-d]-2-oxazoline gave a crystalline, 6-O-substituted disaccharide derivative which, on de-isopropylidenation followed by saponification, produced the disaccharide p-nitrophenyl 6-O-(2-acetamido-2-deoxy-β- d -glucopyranosyl)-α- d -mannopyranoside. Synthesis of methyl 6-O-(2-acetamido-2-deoxy-β- d -glucopyranosyl)-α- d -mannopyranoside was also accomplished by a similar reaction-sequence. The structures of these disaccharides have been established by 13C-n.m.r. spectroscopy.
