Highly alpha-selective glycosylation with glycopyranosyl fluorides having diethylthiocarbamoyl group
Highly alpha-selective glycosylation of various glycosyl accept tors with glucopyranosyl fluoride having diethylthiocarbamoyl, cup at 6 position or galactopyranosyl fluoride having the same group at 4-position proceeded smoothly in the presence of a catalytic amount of protic acid to afford the corresponding disaccharides in high yields.
