Trifluoromethyl‐substituted quinolones and their analogues have emerged as an interesting platform in the last 6 years to design antiparasite agents. Many of their derivatives have been demonstrated to display excellent efficacy against flagellate parasites such as Plasmodium spp. In order to identify new analogues of trifluoromethyl‐substituted quinolones to treat the American cutaneous leishmaniasis,...
A simple protocol is described for the synthesis of 2-(trifluoromethyl)benzo[b][1,8]naphthyridin-4(1H)-one derivatives. The reaction between diverse 2-chloro-3-acetyl-quinolines with trifluoroacetimidoyl chlorides using sodium hydride in THF at room temperature gives directly the title compounds without isolation of intermediates. Starting 2-chloro-3-acetyl-quinolines were easily prepared in two steps...
