Abstract

A concise and efficient one-pot three-component synthesis of structurally diverse fluorine substituted bicyclic pyridines was constructed by simply refluxing a mixture of different types of heterocyclic ketene aminals, triethoxymethane, and fluorine-containing methylene compounds under solvent-free and catalyst-free conditions. These bicyclic pyridines are promising candidates for drug discovery; consequently, a library of fluorine substituted bicyclic pyridines was rapidly constructed in 79%–93% yields.
