Abstract

The outcome from aminolysis of 3,3,9-trichlorothieno[3,4-b]quinolinone with an alkylamine is dependent on the reaction conditions and extraneous reagents employed. A variety of hitherto unreported products can be obtained and include 4-chloro-2-alkylthiocarbamoyl-quinoline-3-carboxylic acid alkylamides, 9-chloro-2-alkyl-3-alkylimino-pyrrolo[3,4-b]quino-lines, 9-chloro-2-alkyl-3- thioxo-pyrrolo[3,4-b]-quinolines, 2-alkyl-3-alkylimino-9-thioxo-pyrrolo[3,4-b] quinolines, and 2-alkyl-9-alkylamino-3-alkylimino-pyrrolo[3,4-b]quinolines. The spectral (1H NMR, HRMS) and chemical properties and the structures of the products are described and discussed, and possible mechanistic pathways leading to their formation are presented.
