Synthesis of 3-Arylimidazo[1,2-a]pyridines by a Catalyst-Free Cascade Process

[摘要]：A simple and efficient protocol to synthesize 3-arylimidazo[1,2-a] pyridines by a catalyst-free cascade process from 2-aminopyridine and 1-bromo-2-phenylacetylene or 1,1-dibromo-2phenylethene in yields up to 86% is described.
