Abstract

Ring-opening allylation of cyclic acetals has required stoichiometric amounts of Lewis acids. In this paper, catalytic ring-opening allylation in the presence of silica-alumina is reported. This ring-opening allylation showed high atom economy. Consecutive allylation/hydrolysis using silica-alumina afforded homoallyloxyalcohols in good to high yields.
