Synthesis of the Benzazepin-4-one Ring System via Dipolar Cycloaddition of N-Phenylnitrones with Activated Allenes

Article abstract of DOI:10.1021/jo00265a018

The 1,3-dipolar cycloaddition of N-phenyl-C-phenylnitrone with several allenes containing electron-withdrawing groups has been investigated.The cycloaddition proceeds in good yields to give a substituted benzazepin-4-one.The structure of the cycloadduct w
