The dibenzylidene derivative of glucose phenylosotriazole

Abstract

The dibenzylidene derivative (m.p. 141°) of D-glucose phenylosotriazole is shown by degradative and p.m.r. evidence to have a 3,4:5,6-di-O- benzylidene structure with two five-membered dioxolan rings. The compound has the R configuration at both acetal carbon atoms.
