Reaction of diphenylketene (I) with azadienes (II-IX), having -C=N-C=N- multiple bond system between carbon-nitrogen double bond in heterocycles and their side-chain carbon-nitrogen double bond, gave the 1,4-cycloadducts (XI-XVIII), respectively. Hydrogenolysis of the 1,4-cycloadducts (XIb, XIIb, and XVIb), with lithium aluminum hydride in tetrahydrofuran gave the 1-propanol derivatives (XIX, XXI, and XXII), respectively. On the other hand, reaction of I with 3-(p-anisylideneamino)-5-phenylisoxazole (Xb) and 2-benzylideneaminopyridine (XXIV) respectively afforded 1-[3-(5-phenylisoxazolyl)]-3,3-diphenyl-4-(p-anisyl)-2-azetidinone (XXIII) and 1-(2-pyridyl)-3,3,4-triphenyl-2-azetidinone (XXV).
