摘要

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.
