Facile and Efficient Synthesis of a New Class of Indole-Substituted Pyridine Derivatives via One-Pot Multicomponent Reactions

[摘要]：A new series of indole-containing pyridine derivatives, 4-aryl-6-(1H-indol-3-yl)-2,2'-bipyridine-5-carbonitriles, were synthesized via one-pot multicomponent reactions of 3-(cyanoacetyl)indoles, aldehydes, heterocyclic ketones, and ammonium acetate. Particularly valuable features of this method include high yields of products, broad substrate scope, and straightforward procedures.
