SYNTHESIS OF HETEROARYLQUINOLINES BY THE PHOTOLYSIS OF 2-, 3-, AND 4-IODOQUINOLINES
Ohkura, Kazue,Seki, Koh-ichi,Terashima, Masanao,Kanaoka, Yuichi
, p. 957 - 962 (2007/10/02)
Photoreaction of 2-, 3-, and 4-iodoquinolines with five membered heterocycles (i.e. 1-methylpyrrole, pyrrole, furan and thiophene) afforded the corresponding n-(2-heteroaryl)quinolines (n=2, 3, 4) in appreciable yields.
