A FRIEDLAENDER APPROACH TO 3-SUBSTITUTED 2,5,8-(1H)-QUINOLINETRIONES
Blanco, Ma del Mar,Avendano, Carmen,Cabezas, Nieves,Menendez, J. Carlos
, p. 1387 - 1398 (2007/10/02)
An efficient method is proposed for the preparation of 3-substituted carbostyrilquinone derivatives, based on Friedlaender synthesis of the 5,8-dialkoxyquinolines followed by cerium ammonium nitrate oxidative demethylation.
