Abstract

Abstract A preparatively useful one-step transformation of γ, γ-disubstituted α-formyl-γ- lactones into trisubstituted γ, δ-unsaturated aldehydes is described, by means of catalytic amounts of either AcOH or AcOEt in the vapor phase over a glass support. A mechanistic rationale is proposed.
