Investigation of 2,3′-biquinolyl. 11. Regioselectivity in the hydroxylation of 1-alkyl-3-(2-quinolyl)quinolinium halides

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.

Investigations of 2,3′-biquinolines 23. Synthesis of 1′-R-1′,4′-dihydro-2,3′-biquinolin-4′-ones by Claisen condensation

A method has been developed for the synthesis of 1′-R-1′, 4′-dihydro-2,3′-biquinolin-4′-ones based on the interaction of quinaldine with N-alkyl-N-formylanthranilic acid methyl esters under the conditions of the Claisen condensation.

Investigations on 2,3′-biquinolines. 18*. New convenient one-pot synthesis of 1′-alkyl-1′,4′-dihydro-2,3′- biquinolyl-4′-thiones and their conversion into 1′-alkyl-1′, 4′-dihydro-2,3′-biquinolyl-4′-ones

A method has been developed for the one pot synthesis of 1′-alkyl-1′,4′-dihydro-2.3′-biquinolyl-4′-thiones based on the reduction of 1-alkyl-3-(2-quinolyl)quinolinium halides with sodium borohydride and subsequent thiolation. 1′-Alkyl-1′,4′-dihydro- 2,3′-
