The present invention relates to O-thiocarbamoyl-aminoalkanol compound represented by the following structural formula (VI), (VIII) and (IX) which are a racemic or enantiomerically enriched and pharmaceulically acceptable salts thereof to treat diseases of the central nervous system: ##STR1## wherein Ar is a phenyl group as described as follows: ##STR2## wherein R is a member selected from the group consisting of hydrogen, lower alkyl of 1 to 8 carbon atoms, halogen selected from F, Cl, Br, and I, alkoxy containing 1 to 3 carbon atoms, thioalkoxy containing 1 to 3 carbon atoms, nitro, hydroxy, or taifluorocarbon, and x is an integer from 1 to 3, with the proviso that R is the same or different when x is 2 or 3. R.sub.1 and R.sub.2 may be the same or different from each other and are independently selected from the group consisting of hydrogen, lower alkyl of 1 to 8 carbon atoms, aryl, 3 to 7-membered aliphatic cyclic compounds and R.sub.1 and R.sub.2, together with the adjoining N-atom, form a 5 to 7-membered cyclic compound which optionally comprises zero to one additional nitrogen atoms substituted with a member selected from the group consisting of hydrogen, alkyl and aryl groups, or zero to one oxygen atoms directly unconnected, R.sub.3 and R.sub.4 may be same or different from each other and are independently selected from the group consisting of hydrogen, lower alkyl of 1 to 8 carbon atoms, aryl, 3 to 7-membercd aliphatic cyclic compounds and R.sub.3 and R.sub.4, together with the adjoining N-atom, form a 5 to 7-membered cyclic compound which optidonally comprises zero to one additional nitrogen atoms substituted with a member selected from the group consisting of hydrogen, alkyl and aryl groups, or zero to one oxygen atoms directly unconnected, each of l, m and n is zero or 1, and the pharmaceutically acceptable salts thereof.
本发明涉及以下结构式(VI),(VIII)和(IX)所表示的O-硫代氨基烷醇化合物及其对治疗中枢神经系统疾病的拟合剂进行的立体异构或富集,其结构式如下:
其中,Ar是如下所述的苯基:
其中,R是从氢,1到8个碳原子的低级烷基,F、Cl、Br和I中选择的卤素,含有1到3个碳原子的烷氧基,含有1到3个碳原子的硫代烷氧基,硝基,羟基或三氟甲基的成员中选择的成员,x是从1到3的整数,但在x为2或3时,R相同时或不同时。R1和R2可以彼此相同或不同,并且独立地选择从氢,1到8个碳原子的低级烷基,芳基,3到7个成员的脂肪环化合物和R1和R2,连同相邻的N原子,形成一个5到7个成员的环化合物,该环化合物可以选择包含零到一个其他氮原子,其被取代为从氢,烷基和芳基组成的成员中选择的一个,或者零到一个直接未连接的氧原子。R3和R4可以相同或不同,并且独立地选择从氢,1到8个碳原子的低级烷基,芳基,3到7个成员的脂肪环化合物和R3和R4,连同相邻的N原子,形成一个5到7个成员的环化合物,该环化合物可以选择包含零到一个其他氮原子,其被取代为从氢,烷基和芳基组成的成员中选择的一个,或者零到一个直接未连接的氧原子。l,m和n中的每一个都是零或1,以及其药学上可接受的盐。
