Enaminones acylation: Competitive formation of quinolin-4-one and isoquinolin-1-one derivatives

Valès,Lokshin,Pépe,Samat,Guglielmetti

, p. 2419 - 2426 (2001)

The reaction of enaminones with some o-halogenobenzoyl chlorides allows the preparation of 3-acyl-2-alkylquinolin-4-one and/or 4-acyl-3-alkylisoquinolin-1-one derivatives depending on the structure of the starting materials. Due to their easy availability the compounds prepared ar.e attractive precursors for further synthesis of polycondensed heterocycles.
