  Synthesis of 7-Substituted Derivatives of 5,8-Dimethylisoquinoline

  摘要：

  7-Bromo-5,8-dimethylisoquinoline was selectively synthesized by the bromination of 5,8-dimethylisoquinoline obtained in five steps from p-xylene as a starting material. Further, 7-bromo-5,8-dimethylisoquinoline gave 7-amino-5,8-dimethylisoquinoline by the reaction with ammonia and various 7-anilino-5,8-dimethylisoquinolines via a palladium-catalyzed coupling reaction with anilines.

  7-amino-5,8-dimethyl-6-(phenylthio)isoquinoline unexpectedly led to the formation of a new ring system, 3H-pyrazolo[3,4-h]isoquinoline as its 5-methyl-6-phenylthio derivative. In this work, the parent ring system was synthesized and characterized, along with its 5-methyl, 6-bromo-5-methyl, and 5-methyl-6-phenylthio derivatives. The mechanism for the transformation is explored.
