The ortho esterification of various glucofuranoses in the D-ribo-, D-xylo and D-gluco series under kinetic control was obtained through the action of 1,1-dimethoxyethene (a ketene acetal) on the monosaccharide using mild acid conditions. The selective hydrolysis of the methoxyethylidene derivatives thus obtained, gave access to α-hydroxy acetates which are useful synthetic intermediates.
