The mechanism of the hydrolysis of glycofuranosides

Abstract
The mechanism of the acid-catalysed hydrolysis of a series of aldofuranosides has been investigated. These reactions are shown to involve glycosyl–oxygen fission and an initial rapid proton-transfer. The entropies of activation, which are all negative, are interpreted in terms of either a bimolecular displacement of MeOH or EtOH by H2O, or a mechanism involving ring-opening.
