  Synthesis of N-Alkyl-Substituted 4-Quinolones via Tandem Alkenyl and Aryl C-N Bond Formation

  摘要：

  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.

  and direct approach for constructing 4-quinolones from simple and readily available anilines and alkynes is described. Under the optimal conditions, both N-alkyl- and N-aryl-substituted anilines can be successfully transformed into the corresponding 4-quinolones. This reaction is characterized by mild reaction conditions, high functional-group tolerance, and amenability to gram-scale synthesis.

  1,2-Disubstituted 4-quinolones have been prepared via copper-catalyzed heterocyclization of 1-(2-bromophenyl)- and 1-(2-chlorophenyl)-2-en-3-amin-1-ones, readily obtained from α,β-ynones and primary amines. The reaction tolerates a variety of useful functionalities including ester, keto, cyano, and chloro substituents. Quinolone derivatives can also be prepared via a sequential process from α,β-ynones and primary amines, omitting the isolation of the 1-(2-halophenyl)-2-en-3-amin-1-one intermediates.
