R, = radical organique C 1-18 comportant éventuellement un ou plusieurs hétéroatomes ; R 2 = radical hydrocarboné C 1-8 ; R 3 et R 4 forment ensemble le radicaln les cycles A et B représentent les groupements :n n R' et R" = H, CN ou Alkyle C 1-4 ; Rx = H ou ORe; Re = H, alkyle C 1-6 ou acyle;n R'a et R"a = Alk C 1-4 soit R'a et R"a forment un hétérocycle ou Ra = acyloxy; leur procédé de préparation, leur application comme médicaments, les compositions les renfermant et les nouveaux intermédiaires obtenus. The subject of the invention is the products of formula (I) in which : R, = organic radical C 1-18 optionally comprising one or more heteroatoms; R 2 = C 1-8 hydrocarbon radical; R 3 and R 4 together form the radical cycles A and B represent the groupings: R 'and R "= H, CN or C 1-4 alkyl; Rx = H or ORe; Re = H, C 1-6 alkyl or acyl; R'a and R "a = Alk C 1-4 either R'a and R" a form a heterocycle or Ra = acyloxy; their preparation process, their application as medicaments, the compositions containing them and the new intermediates obtained. |
