Using PdCl2(PhCN)2-SnCl2, enol esters caused aldol-typecondensation with aldehydes at 50°C in acetonitrile to produce (E)-α,β-unsaturated carbonyl compounds. Cyclic enol ester such as α-angelicalactone also reacted with aldehydes under the same conditions to afford γ-substituted β-acetyle-γ-butyrolactones and/or 5-substituted 4-acetyl-2(5H)-furanones.
