  Synthesis of novel tetrahydrobenzazepinones

  摘要：

  The synthesis of novel tetrahydrobenzazepinones 1, 2, and 3 is described, as well as an improved synthesis of 4. The palladium catalyzed arylation approach to 1, 2, and 4 allows facile entry to benzazepinones lacking electron donating substituents on the benzo ring.

  ambient temperature resulted in acid-promoted hydration and sequential intramolecular aldol condensation reactions to afford 3-aryl-1H-inden-1-one derivatives in good yields. The proposed reaction mechanism was strongly supported by the reaction behaviour of 4-chloro- and 5-methoxy-2-ethynylbenzophenone derivatives as substrates with Tf2NH, leading to the formation of the corresponding 3-aryl-1H-inden-1-ones
