Indium‐Catalyzed Cycloisomerizations of Cyclopropene‐3,3‐Dicarbonyl Compounds: Efficient Access to Benzo‐Fused Heteroaromatics and Heterobiaryls

Abstract

Rapid access: The title reaction generates highly functionalized benzo-annulated heterocycles and heterobiaryls. This method is amenable to a diverse array of heteroaromatics, thus allowing rapid access to benzothiophenes, benzofurans, indoles, indolizines, and pyrido[1,2-a]indoles (see scheme; Tf=trifluoromethanesulfonyl).
