Synthesis of 3-amino-4,5-dihydro(5H)4-oxothieno[3,2-c]quinoline-2- carboxylic acids and their alkyl esters

4-Hydroxyquinolin-2(H)ones are converted to 4-chloro-3-cyanoquinolin-2(H) ones and are cyclised with thioglycolic acid and its alkyl esters to furnish the title compounds viz. 3-amino-4,5-dihydro(5H)4-oxothieno[3,2-c]quinoline-2- carboxylic acids and thei

Synthesis of 4-hydroxy-3-formylideneamino-lH/methyl/phenylquinolin-2-ones

An efficient method for the synthesis of 4-hydroxy-3-formylideneamino-l H/methyl/phenylquinolin-2-ones by the condensation of corresponding 4-hydroxy-3-formyl-l///methyl/phenylquinolin-2-one with substituted anilines/aliphatic primary amines is reported. The carboxaldehyde in turn is prepared starting either from substituted anilines or benzoic acid. The structures of compounds are established by the elemental analysis and spectral data.
