yields to the 2,2-disubstituted 1,2-dihydro-4-phenyl-quinolines 1–18 (Scheme 1, Table). The structure of the new racemic 1,2-dihydroquinolines 1–18 is determined by NMR spectroscopy. A reaction mechanism proceeding via a 6π-electrocyclic rearrangement of 2-(1-phenylvinyl)anils 19 as the key step is proposed for the formation of these compounds (Scheme 1). The scope and limitations of the novel methods are

A facile and efficient approach toward the synthesis of functionalized quinolines and 1,2‐dihydroquinolines from carbonylcompounds and 2‐vinylanilines is described. The protocol utilizes the nonhazardous and less expensive FeCl3 as catalyst with wide functional group tolerance and avoiding heavy metal impurities in the products.
