Abstract

3-Acety1-5-benzoy1-6-methy1-2-pheny1-4H-pyran-4-one has been subjected to condensation with a series of primary amines (ethylamine - octylamine) to clarify the proposed mechanism in our previous study. The reactions of the shorter amines of the series (ethylamine - butylamine) yielded unsymmetric pyridinone products, whereas the other amines (pentylamine - octylamine) yielded symmetrical pyridinones. The starting material and the products as well as the intermediates have been subjected to theoretical analysis by quantum chemical calculations at B3LYP/6-3 I G(d,p) level, which provided supporting data for the experimental findings.
