title: Highly stereoselective alpha-O-glucosylation of heterocyclic ketene aminals.
abstract: A new series of alpha-glucosides of heterocyclic ketene animals have been synthesized. The double bonds of the glucosides resulted in Z or E configuration by using CaH2 or a Lewis acid as catalyst, respectively. A special complex of mercuric cyanide with glucopyranosides was the result when Hg(CN)2 was used to catalyze the reaction.
