Abstract

A highly diastereoselective tandem ring-enlargement and aldol condensation process involving multicomponent reactions of ethereal tricyclooxonium ylide intermediate with alcohols, mono-or dialdehydes in the presence of titanium (IV) isopropoxide is described to furnish alkoxyoctahydro-1, 4-benzodioxocin-6 (5H)-one ring systems.
