- 論文の詳細を見る
1,2-Diaminopyridinium mesitylenesulfonate (I) reacts, in the presence of potassium carbonate, with a variety of α, β-unsaturated carbonyl compounds such as benzoylacetyllenes, benzalacetophenones, ethoxymethylenepentane-2,4-dione, and diethyl ethoxymethylenemalonate to give s-triazolo[1,5-a]pyridine derivatives, presumably via 1-amino-2-imino-1,2-dihydropyridine (VIII). Reaction of I with diphenylcyclopropenone in ethanol in the presence of potassium carbonate afforded ethyl 3-amino-2,3-diphenylacrylate, whereas reaction of VIII in an aprotic solvent (benzene) gave 3-amino-2,3-diphenyl-N-(2-pyridyl)acrylamide.
