4-Quinolone and 4 H -thiochromen-4-one derivatives are readily synthesized in a tandem one-pot manner in good to excellent yields. Starting from (Z)-β-chlorovinyl ketones, an intermolecular nucleo-philic addition of amines or sodium hydrogen sulfide to (Z

A convenient approach has been developed for the construction of quinolin-4(1H)-one frameworks, starting from (Z)-β-chlorovinyl aromatic ketones and amines. Intermolecular Michael addition of an amine to a (Z)-β-chlorovinyl ketone was followed by eliminat

N-Alkyl-substituted 4-quinolones are present as the key structural motif in many marketed drugs. An efficient one-step tandem amination approach was developed to afford N-alkyl-substituted 4-quinolones in high yields from easily accessible o-chloroaryl acetylenic ketones and functionalized alkyl amines. The approach complements and extends our previous work. Compared with other reported methods, the current method provides a very simple and convenient route.
