Iodine-Catalyzed Simple and Efficient Synthesis of 1,3,5-Triarylbenzenes and 2,3-Dihydrobenzofuran Derivatives under Mild Reaction Conditions

Abstract

AbstractThe I2-catalyzed cyclization reaction of chalcones and 2-aryl propionaldehydes or isobutyraldehyde has been developed for the synthesis of 1,3,5-triarylbenzenes and 2,3-dihydrobenzofuran derivatives. This reaction tolerates a wide range of functional groups. Moreover, this method features an inexpensive catalyst and available starting materials.
