Abstract

Abstract The reaction of 1, 3-diaryl-2-propene-1-ones I with arylacetamides II, in the presence of sodium ethoxide under reflux, for two hours, gave the corresponding 3, 4, 6- triaryl-3, 4-dihydro-2 (1H)-pyridones IV. However, when the reaction of these ketones was carried out in the presence of sodium hydride, they gave the corresponding 3, 4, 6-triaryl-2 (1H)-pyridones VI or a mixture of IV and VI. When 1, 3-diaryl-2-propyne-1-ones V were ...
