4-Quinolone fused heterocyclic ring systems by intramolecular reactions of 4-quinolone-2-carboxamides [PDF]
Tetrahedron, 2014 Abstract A versatile synthetic route to new 4-quinolone-based polycyclic systems is described. TFA-catalyzed intramolecular reaction of N-unsubstituted quinolone-2-carboxylic acid amides gives structurally diverse compounds, depending on the length of the chain.
