Novel synthesis of Disaccharides containing the 2-amino-2-deoxy-beta-D-glucopyranosyl unit and L-glycero-D-manno- and 7-deoxy-L-glycero-D-galacto-heptopyranoses
Stereocontrolled syntheses of immunologically relevant heptopyranose disaccharides were achieved in excellent yields by the trimethylsilyl triflate promoted glycosylation of the donor 1,3,4,6 -tetra-O-acetyl-2-N-allytoxycarbonyl-2-amino-2-deoxy-beta-D-glucopyranos e with the adequate acceptors.
