Transformations of 2-aryl-4-(2-oxopyrrolidinyl-1)-1,2,3,4-tetrahydroquinolines, cycloadducts of the BiCl3-catalyzed three-component Povarov reaction: Oxidation and reduction processes towards new potentially bioactive 2-arylquinoline derivatives

Synthesis and spectral characterization of new series of 2‐aryl‐4‐(2‐oxopyrrolidinyl‐1)‐1,2,3,4‐tetrahydroquinolines and their aromatic analogs, 2‐arylquinolines are reported. It was found that substituted tetrahydroquinoline precursors are easily prepared using BiCl3‐catalyzed three‐component Povarov reaction between 4‐nitrobenzaldehyde or 2‐naphtylcarboxyaldehyde, anilines and N‐vinylpyrrolidin‐2‐one

Photochemically promoted Diels-Alder reactions of N-arylimines with N-vinylpyrrolidinone and N-vinylcarbazole were achieved by using 2,4,6-triphenylpyrylium tetrafluoroborate as a catalyst to produce corresponding 2-oxopyrrolidin-1-yl and carbazol-9-yltetrahydroquinolines in high yields.
