✦ Synopsis

Thioglycoside and trichloacetimidate donors show the same regiopreferences as NPG analogs for selective glycosidation of an altroside diol, indicating that the selectivity may be general for donors. They also undergo one-pot, double-differential-glycosidations to give a single trisaccharide out of four possibilities.
