- 論文の詳細を見る
Reaction of several conjugated C-N double bond compounds with diketene was carried out with a view to establishing the structure-reactivity relationship of the 1,3-diaza-1,3-butadiene system. Formamidine derivatives (IIIa-h) reacted with diketene in benzene to form the products (Va-h) through 1,4-dipolar cycloaddition with the elimination of dimethylamine, respectively. Similarly, reaction of diketene with 2-(p-dimethylaminobenzylideneamino) benzothiazole (IXa) and 2-(p-dimethylaminobenzylideneamino) benzimidazole (IXb) respectively afforded 3-acetyl-2-(p-dimethylaminophenyl)-2,3-dihydro-4-oxo-4H-pyrimido [2,1-b] benzothiazole (Xa) and 3-acetyl-2-(p-dimethylaminophenyl)-2,3-dihydro-4-oxo-4H-pyrimido-[1,2-a] benzimidazole (Xb).
