One-Pot Three-Component Synthesis of Benzo[ f]thiopyrano[3,4- b]quinolin-11(8 H)-one Derivatives.

A series of novel benzo[ f]thiopyrano[3,4- b]quinolin-11(8 H)-one derivatives were synthesized via the reaction of aryl aldehyde, 2 H-thiopyran-3,5(4 H,6 H)-dione, and β-naphthylamine in glacial . This protocol features mild reaction conditions, high yields, and short reaction time. [ABSTRACT FROM AUTHOR]
