A NOVEL PHOTO-INDUCED SUBSTITUTION OF ALKYL 2-CYANO-3-QUINOLINECARBOXYLATES

Article abstract of DOI:10.1246/cl.1989.371

Irradiation of 2-quinolinecarbonitriles having an alkoxycarbonyl group at the 3-position afforded five-membered and/or six-membered lactones in normal alcohols depending on their alkyl-chain-length, whereas the irradiation in 2-propanol and t-butyl alcohol did not cause any cyclization, but instead decyanated and methylated products were obtained, respectively.
