## Abstract 1โSubstitutedโ3โdimethylaminopropenones **1aโd** reacted with acetylacetone and with ethyl acetoacetate to yield regioselectively 2,3,6โtrisubstituted pyridines. Refluxing **1aโd** in acetic acid/ammonium acetate resulted in the formation of 6โsubstitutedโ3โaroylpyridines, whereas reflu
