摘要：

Treatment of 1,2,3,4,6-penta-O-acetyl-β-D-glucopyranose with silicon tetrachloride in 1,2-propanediol carbonate gave 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl chloride and 4,6-di-O-acetyl-3-O-[1-(chloromethyl)ethyl]-2-deoxy-β-D-ribo-hexopyranosyl 4,6-di-O-acetyl-3-O-[1-(chloromethyl)ethyl]-2-deoxy-β-D-ribo-hexopyranoside. The structure of the disaccharide was established mainly by i.r., n.m.r,...
