  Intramolecular cyclisation of functionalised heteroaryllithiums. Synthesis of novel indolizinone-based compounds

  摘要：

  The intramolecular cyclisation of heteroaryllithiums derived from N-heteroarylmethylpyrrole-2-carboxam ides takes place smoothly at low temperature when N-methoxy-N-methyl and morpholine amides are used as internal electrophiles. Halogen-lithium exchange using n-BuLi is the method of choice to achieve metalation on the quinoline and pyridine derivatives, while directed lithiation (LDA) works better for furan. In the case of thiophene both methodologies can be applied. These metalation-cyclisation sequences provide a useful entry to several types of indolizidine based compounds (pyrrolo[1,2-b]acridinones, pyrrolo[1,2-g]quinolones, thieno and furo[3,2-f]indolizinones).

  [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.
