    摘要: A method of synthesizing nitrogen heterocycles such as indoles, indolines, oxindoles, quinolines, isoquinolines, and isoquinolones, all of which are pharmacologically active. The method involves cyclizing a haloaryl alkene in the presence of a catalytically effective amount of a palladium(II) ion source and in the presence of a cyclizing promoting base such as an alkali metal salt.
