  An efficient entry to pyrrolo[1,2-b]isoquinolines and related systems through Parham cyclisation

  摘要：

  Aryllithiums generated by lithium-iodine exchange undergo intramolecular cyclisation to give pyrrolo[1,2-b]isoquinolines, in high yields. The best results were obtained when Weinreb or morpholine amides were used as internal electrophiles. The procedure has been extended to the preparation of seven and eight membered rings, opening a route to benzazepine and benzazocine skeletons. (c) 2004 Elsevier Ltd. All rights reserved.

  Parham-type cyclisation of N-(o-halobenzyl)pyrroles has been investigated. Aryllithiums generated from metalation of N-(o-iodobenzyl)pyrroles undergo intramolecular cyclisation to give pyrrolo[1,2-b]isoquinolinones in moderate to good yields, if the N,N-diethylcarbamoyl group is used as internal electrophile and the aromatic ring is activated.

  已经研究了N-（邻卤代苄基）吡咯的Parham型环化。如果将N，N-二乙基氨基甲酰基用作内部亲电试剂和芳环，则由N-（邻碘苄基）吡咯金属化生成的芳基锂分子内环化，可以中等至良好的产率得到吡咯并[1,2- b ]异喹啉酮被激活。

  [GRAPHIC]Weinreb amides behave as efficient internal electrophiles in Parham-type cycliacylation reactions. Thus, aryl- and heteroaryllithiums generated by lithium-halogen exchange undergo intramolecular cyclization to give fused indolizinone systems as pyrrolo[1,2-b]isoquinolines, thieno[2,3-f]indolizinones, and pyrrolo[1,2-b]acridinones in high yields.
