alfa-Methylene-beta-lactams possessing a Z-alkoxycarbonyl group are formed directly from the reaction of N-alkyl-substituted prop-2-ynylamines with CO, air and alcohols, under the catalytic action of palladium on carbon in conjunction with potassium iodide, while gamma-lactams or oxazolines are obtained with unsubstituted or acylated amines.
