摘要：

The hydroxylation of 1-alkyl-3-(2-quinolyl)quinolinium halides by an alkaline solution of K3[Fe(CN)6] in aqueous 1,4-dioxane leads to a mixture of 1-alkyl-3-(2-quinolyl)-1,2-dihydro-2-quinolones and 1-alkyl-3-(2-quinolyl)-1,4-dihydro-4-quinolones with predominance of the former. The use of the system of K3[Fe(CN)6]/Mg(OH)2 in aqueous 1,4-dioxane leads to the regiospecific formation of 1-alkyl-3-(2-quinolyl)-1,4-dihydro-4-quinolones.
