    摘要: Thiocarbamates are prepared by a process comprising reacting an aqueous solution of a thiocarbamate salt with an organic halide in the presence of a catalytic amount of a quaternary ammonium salt having the formula
    in which R 4 and R 5 are independently selected from the group consisting of C 1 -C 25 alkyl and C 2 -C 25 alkenyl, R 6 and R 7 are independently selected from the group consisting of C 6 -C 25 alkyl and C 6 -C 25 alkenyl, and Y- is an anion selected from the group consisting of chloride and bromide; and separating the thiocarbamate from the aqueous solution.

    摘要: Dérivé de 2-méthylènepropane-1,3-diol, représenté par la formule générale (I), dans laquelle O-A1 et O-A2, qui peuvent être analogues ou différents, représentent chacun O, OC(O), OC(O)NH, OC(S)NH ou OC(O)O, R1 représente un groupe d'alkyle ou d'alkényle de 10-22 atomes de carbone, n est un nombre entier compris entre 1 et 11, B+ représente un groupe d'ammonium quaternaire, qui est soit NR4R5R6 soit N(Het), dans lequel R4, R5 et R6 sont des groupes alkyle analogues ou différents de 1-4 atomes de carbone, ou dans lequel R4, R5 et R6 peuvent tous les trois ou seulement deux d'entre eux être incorporés dans une structure cyclique ou bicyclique, laquelle peut contenir des atomes hétérogènes supplémentaires; X- représente l'anion d'un acide inorganique ou organique pharmaceutiquement acceptable; et R2 et R3 sont analogues ou différents et représentent des groupes d'hydrogène ou d'alkyle de 1-4 atomes de carbone. Lesdits composés ont révélé avoir un effet inhibiteur sur l'activité du facteur d'activation des thrombocytes (PAF) et sur la croissance des cellules tumorales. Ils peuvent par conséquent être utilisés efficacement, aussi bien en médecine humaine qu'en médecine vétérinaire, comme inhibiteurs de l'aggrégation des thrombocytes, comme agents de lutte contre la thrombose, l'asthme, les allergies, les inflammations, l'hypotension, les ulcères, le psoriasis, le rejet des greffes, les tumeurs, ainsi que comme agents contraceptifs.

    摘要: The present invention relates to a process forthe preparation of thiocarbamates having the general formula:
    where:
    R represents a C 1 -C 4 alkyl optionally substituted with one or more halogen atoms, a C 2 -C 4 alkenyl optionally substituted with one or more halogen atoms, a phenyl optionally substituted with one or more halogen atoms, a benzyl optionally substituted with one or more halogen atoms in the phenyl portion; R' and R 2 , equal or different from each other, represent a C 1 -C 4 alkyl, a cycloalkyl.

    摘要: A derivative of 2-methylenepropane-1,3-diol of general formula (I), where O-A1 and O-A2, which can be the same or different, each represents O, O-C(O), O-C(O)NH, O-C(S)NH or O-C(O)O, R1 represents an alkyl or alkenyl group of 10 - 22 carbon atoms, n is an integer from 1 to 11, B+ represents a quaternary ammonium group, either NR4R5R6, or N(Het), where R4, R5 and R6 are similar or different alkyl groups of 1 - 4 carbon atoms, or two or all of R4, R5 and R6 may be incorporated into a cyclic or bicyclic structure, which may contain additional hetero atoms; X- means the anion of a pharmaceutically acceptable inorganic or organic acid; and R2 and R3 are the same or different, and represent hydrogen or alkyl groups of 1 - 4 carbon atoms. The present compounds have been shown to possess a PAF antagonistic effect and an inhibitory effect on the growth of tumor cells, and are thus valuable in the human and veterinary practice as platelet aggregation inhibitors, anti-thrombotic agents, anti-asthmatic agents, anti-allergic agents, anti-inflammatory agents, anti-hypotensive agents, anti-ulcer agents, anti-psoriatic agents, anti-graft rejection agents, anti-conception agents and anti-tumor agents.
