in dienyl glycosidesallowed us to rationalize the stereochemistry of our aqueouscycloadditions usingglyco-organicsubstrates. In this way, several dienyl glucosides having benzyl group in 2 or 6 position of the sugar gave a stereofacial selectivity which could beanticipated. Finally, aqueouscycloaddition of 2-methyl butadienyl α-D-glucoside with methacrolein gave a mixture ofadducts in which the major
