Reactions of bisulfite addition compounds prepared in situ from cyclohexanone or 3,4,5,6-tetrahydro-2H-thiopyran-3-one with potassium cyanide and corresponding amines resulted with high yields in amino nitriles type of V and VI. These compounds were subjected to reactions with 2-thienylmagnesium bromide and in the case of the amino nitriles Vc and Vf with 5-bromo-2-thienylmagnesium bromide. Only in the case of compound Vf, a by-product X was isolated in addition to the desired 1-[1-(5-bromo-2-thienyl)-1-cyclohexyl]piperidine (VIIf). Compound VIIf was used for the synthesis of the carboxylic acid XI. The compounds prepared were tested by some methods of biochemical and behavioural pharmacology.
通过从环己酮或3,4,5,6-四氢-2H-硫吡喃-3-酮与氰化钾和相应胺反应制备的亚硫酸氢盐加合物,在高收率下生成了氨基腈类的化合物V和VI。这些化合物经过与2-噻吩基镁溴化物的反应,以及在氨基腈Vc和Vf的情况下与5-溴-2-噻吩基镁溴化物的反应。只有在化合物Vf的情况下,除了所需的1-[1-(5-溴-2-噻吩基)-1-环己基]哌啶(VIIf)之外,还分离出了副产物X。化合物VIIf被用于合成羧酸XI。制备的化合物经过一些生化和行为药理学方法进行了测试。
