Abstract

A solvent-free and efficient synthesis of 14-aryl-14 H-dibenzo[ a, j]xanthenes through the one-pot condensation of β-naphthol and aldehydes catalyzed by recyclable and reusable Iron(III) triflate was reported. Notably, the presented method features short reaction time, excellent yield, and simple experimental procedure. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: A new cascade strategy to the synthesis of 2,3-diarylated indoles via the metal-free reaction of aryl aldehyde and aryl amine triggered by N-heterocyclic carbene (NHC) under solvent-free conditions, has been disclosed. The protocol has the advantages of easy work-up, high yields, wide application scope, and an environmentally benign procedure compared with the reported methods. [Copyright &y& Elsevier]
