  A Concise Synthesis of 3-Arylated Di- and Tetrahydro-2H-2-benzazepin-1-ones; A New Synthetic Approach to the Homoprotoberberine Framework

  摘要：

  A variety of 3-arylated di- and tetrahydro-2H-2-benzazepin-1-ones were efficiently assembled through a sequence involving a Suzuki-Miyaura cross-coupling reaction with enol phosphates derived from the corresponding benzazepine-1,3-diones. This technique has been further exploited for the construction of the homoprotoberberine skeleton, which was readily accessed by intramolecular carbocationic annulation reaction applied to a suitably substituted precursor.
