Abstract
Various ethyl 2-(3-cyanoallylidene)- or 2-[3-(ethoxycarbonyl)allylidene]-1,2-dihydropyridin-1-ylacetates were prepared from the reactions of 1-(1-ethoxycarbonylalkyl)-2-methylpyridinium halides with activated ethoxymethylidene compounds in the presence of a base. The treatment of these 2-allylidene-1,2-dihydropyridine derivatives with acetic acid at the reflux temperature gave directly the title compounds in low to moderate yields.
