There are described compounds of the formula ##STR1## where --R is ##STR2## --R.sub.3 and R.sub.3 being independently --H, loweralkyl, --CHO, --CH.dbd.CH.sub.2, --CH.dbd.CH--loweralkyl, --CH.dbd.CHCO.sub.2 C.sub.2 H.sub.5, --CH.sub.2 N(C.sub.2 H.sub.5).sub.2 or ##STR3## --R.sub.1 when existent is --H, loweralkyl, --CH.sub.2 C.tbd.CH, ##STR4## R.sub.5 being methyl or phenyl optionally mono-substituted with loweralkyl or loweralkoxy; --R.sub.2 when existent is loweralkyl or --CH.sub.2 C.tbd.CH; --X is --H, loweralkyl, loweralkoxy, halogen or trifluoromethyl; and the two --Y groups when existent are both --H, or combine to constitute --(CH.sub.2).sub.4 --; which compounds are useful as analgesic agents, and for treating various memory dysfunctions characterized by decreased cholinergic function such as Alzheimer's disease.
描述了化合物的结构式为##STR1##其中--R是##STR2##--R.sub.3和R.sub.3独立地为--H,较低烷基,--CHO,--CH.dbd.CH.sub.2,--CH.dbd.CH--较低烷基,--CH.dbd.CHCO.sub.2 C.sub.2 H.sub.5,--CH.sub.2 N(C.sub.2 H.sub.5).sub.2或##STR3##--R.sub.1存在时为--H,较低烷基,--CH.sub.2 C.tbd.CH,##STR4##R.sub.5为甲基或苯基,可选择地单取代为较低烷基或较低烷氧基;--R.sub.2存在时为较低烷基或--CH.sub.2 C.tbd.CH;--X为--H,较低烷基,较低烷氧基,卤素或三氟甲基;当两个--Y基团存在时,它们都是--H,或者结合形成--(CH.sub.2).sub.4--;这些化合物可用作镇痛剂,并用于治疗由乙酰胆碱功能降低所表现出的各种记忆功能障碍,如阿尔茨海默病。
