Abstract The reactivity of a series of primary and secondary sugar trityl ethers in tritylcyanoalkylidene condensation has been determined. It was found that the stereoselectivity of glycosylation by this method does not directly depend on the reactivity of the trityl ethers. Based on the results obtained, a stepwise mechanism rather than a concerted mechanism has been chosen as the most probable.
