A series of novel 8‐aminoquinolines (8‐AQs) with an aminoxyalkyl side chain were synthesized and evaluated for in vitro antiplasmodial properties against asexual blood stages, liver stages, and sexual stages of Plasmodium falciparum. 8‐AQs bearing 2‐alkoxy and 5‐phenoxy substituents on the quinolinering system were found to be the most promising compounds under study, exhibiting potent blood schizontocidal

(EN) The invention relates to novel intermediates and processes for the preparation of quinoline compounds useful as anti-malarial drugs and novel intermediates useful in the process. A process for the preparation of a compound of formula (I) in which R1 is C1-6 alkyl; R2 and R3 are independently hydrogen, halogen, trifluoromethyl or C1-6 alkoxy; R4 is C1-6 alkyl; R5 is hydrogen or C1-6 alkyl; and R6 is nitro or amino which comprises reacting a compound of formula (II) in which R1, R4 and R5 are as defined in formula (I) and X is a leading group with a compound of formula (III).(FR) Cette invention concerne de nouveaux produits intermédiaires et des procédés de préparation de composés de quinoline utiles en qualité de médicaments anti-paludiques, ainsi que de nouveaux produits intermédiaires utilisés dans ce procédé. Cette invention concerne un procédé de préparation d'un composé de formule (I) où R1 représente alkyle C1-6; R2 et R3 représentent indépendamment hydrogène, halogène, trifluorométhyle ou alcoxy C1-6; R4 représente alkyle C1-6; R5 représente hydrogène ou alkyle C1-6; et R6 représente nitro ou amino. Ce procédé consiste à faire réagir un composé de formule (II) où R1, R4 et R5 sont tels que définis dans la formule (I) et X est un groupe partant, avec un composé de formule (III).
