Intramolecular nitrone- and azomethine ylidecycloaddition reactions at the periphery of pyrido[1,2-a]pyrimidin-4(4H)-one system

Intramolecular nitrone- and azomethine ylidecycloaddition reactions at the periphery of pyrido[1,2-a]pyrimidin-4(4H)-one system

Isoxazolo[4′,3′:4,5]pyrido- and pyrrolo[2′,3′:4,5]pyrido-[2,3-d]pyrido[1,2-a]-pyrimidines were obtained in the intramolecular cycloaddition reactions of the nitrone and azomethine ylide at the periphery of pyrido[1,2-a]pyrimidin-4(4H)-one system, respectively.
