A new strategy was developed to synthesize 1,2-disubstituted 4-quinolones in good yield starting from 1,3-bisaryl-monothio-1,3-diketone substrates. The synthesized compounds were evaluated for antimalarial activity using Plasmodium falciparum strains. All compounds, except for two, showed good activity. Of these, seven compounds exhibited an excellent antimalarial activity (IC50, 50, >50 μM). This journal is

Herein, the transition-metal-free economical solid phase synthesis of 1,2-disubstituted 4-quinolones has been developed via the novel regiospecific synthesis of enaminones. Notably, a wide range of enaminones were synthesized via a silica-supported solid-
Buchwald-Hartwig coupling/Michael addition reactions: One-pot synthesis of 1,2-disubstituted 4-quinolones from chalcones and primary amines

experimental part, p. 3001 - 3008 (2012/07/13)
The Buchwald-Hartwig coupling/Michael addition sequence has been successfully applied to the synthesis of functionalized 1,2-disubstituted 4-quinolones using Pd(OAc)2 as a catalyst and PPh3 as a ligand. Under these conditions, the intermediate products first formed from chalcones and primary amines underwent catalytic dehydrogenation to yield the 1,2-disubstituted 4-quinolones. Copyright
