We identified a novel class of 4-aminoquinoline-trifluormethyltriazolines as potential antiplasmodial agents. The compounds were accessed through a silver-catalyzed three-component reaction of trifluorodiazoethane with in situgenerated Schiff base from corresponding quinolinylamine and aldehydes. Four of the 32 compounds showed promising antimalarial activity: IC50 values 4–20 nM against Pf3D7 (c
