Abstract

Abstract α, β-Unsaturated carbonyl compounds and butenolides are readily prepared by the rhodium (I) catalyzed isomerization of 1, 3-diene monoepoxides and α-alkylidene-γ- butyrolactones, respectively. The former transformation is formally regarded as the equivalent of a regiospecific aldol condensation of an unsymmetrical ketone.
