Abstract

Afin de réaliser la synthèse de molécules ayant une action anti-ulcère, spécifiquement la rénitidine, la nipérotidine et la cimétidine, ayant la formule (V) où R1 est hydrogène ou ensemble avec R2 représente le reste d'un anneau cycloaliphatique ou hétérocyclique facultativement substitué, ayant 5 ou 6 atomes de carbone, R2 représente H, alkyle, alkyle substitué par un anneau aromatique simple ou substitué, ou par un anneau hétérocyclique substitué, Ar représente un groupe phényle simple ou substitué, un groupe aromatique hétérocyclique simple ou substitué, n = 1, 2, 3, 4, 5 ou 6 et X représente CH-NO2, S, N-C=N, le composé (II) est préparé en suivant la séquence de traitement suivante: (II) où Z= H, NO2 halogène et R3= -(CH2)n Ar, -(CH2)n -SH, - (CH2)n - S - S- (CH2)n, - (CH2)n- S - CH2Ar, Y étant halogène. L'urée de la formule (II) est transformée dans un premier stade pour obtenir le carbodiimide correspondant (VI) par réaction avec de la triphénylphosphine et du brome en présence d'une forte base, et dans un deuxième stade le composé souhaité est obtenu par réaction avec du nitrométhane ou avec un dérivé salin de cynamide.
