title: Glycosylation catalyzed by a chiral Brønsted acid.
abstract: The use of a chiral Brønsted acid catalyst for the activation of trichloroacetimidate glycosyl donors has been demonstrated for the first time. In toluene the chirality of the acid catalyst is seen to influence the stereochemical outcome of the glycosylation processes, hinting that perhaps diastereocontrol of glycosylation processes may become achievable through the judicious use of chiral organic catalysts.
