The present invention relates to novel compounds of the following formula: ##STR1## individual isomers and pharmaceutically acceptable acid addition salts thereof, wherein R.sup.1 is hydrogen, alkyl or phenyl-lower alkyl, in which the phenyl group may be substituted with halogen, lower alkyl or lower alkoxy; R.sup.2 is alkyl, alkenyl, alkynyl, branched or unbranched, with 1-6 carbon atoms inclusive, which group may be optionally substituted with fluoro, hydroxy or phenyl optionally substituted with halogen, trifluoromethyl, lower alkyl, hydroxy or lower alkoxy; R.sup.3 and R.sup.4 are the same or different, and each represents hydrogen, alkyl(1-6 C-atoms), cycloalkyl (3-6 C-atoms), phenyl optionally substituted with halogen trifluoromethyl, lower alkyl, hydroxy or lower alkoxy, or phenyl-lower alkyl, in which the phenyl group may be substituted with halogen, trifluoromethyl, lower alkyl, hydroxy or lower alkoxy. The invention moreover relates to methods for the preparation of the compounds of formula I, to novel intermediates, to pharmaceutical compositions containing same and to methods for the treatment of disorders, caused by malfunction of the acetylcholine (AcCh) or muscarinic system, by administering a non-toxic effective amount of a compound of formula I.
本发明涉及以下式的新化合物:##STR1## 其中R.sup.1是氢、烷基或苯基-低烷基,其中苯基可以被卤素、低烷基或低烷氧基取代;R.sup.2是烷基、烯基、炔基、支链或直链,含1-6个碳原子,该基团可以选择性地被氟、羟基或苯基取代,该苯基可以被卤素、三氟甲基、低烷基、羟基或低烷氧基取代;R.sup.3和R.sup.4相同或不同,分别表示氢、烷基(1-6个C原子)、环烷基(3-6个C原子)、苯基,该苯基可以被卤素三氟甲基、低烷基、羟基或低烷氧基取代,或苯基-低烷基,其中苯基可以被卤素、三氟甲基、低烷基、羟基或低烷氧基取代。此外,本发明还涉及制备式I化合物的方法、新的中间体、含有该化合物的制药组合物以及通过给予式I化合物的非毒性有效量治疗由乙酰胆碱(AcCh)或肌动系统失调引起的疾病的方法。
