A simple and efficient method for regioselective synthesis of 3-arylquinolines is described from α-aminoacetophenones and trans-β-nitrostyrenes using 20 mol% iodine monobromide as a catalyst in acetonitrile solvent at 80 °C. The present method involves tandem reaction of α-aminoacetophenones and trans-β-nitrostyrenes, formation of two new C–C bonds and cleavage of one C–C bond in a single step. The

A novel iron-promoted tandem reaction of anilines with styrene oxides via C-C cleavage and C-H activation has been developed. The reaction utilizes an inexpensive FeCl3 as promoter and is suitable for forming a variety of 3-aryiquinolines from the simple and readily available starting materials.
