The present invention relates to novel compounds of the following formula: ##STR1## individual isomers and pharmaceutically acceptable acid addition salts thereof, wherein R.sub.1 is hydrogen, alkyl or phenyl-lower alkyl, in which the phenyl group may be substituted with halogen, lower alkyl or lower alkoxy; R.sub.2 is alkyl, alkenyl, alkynyl or phenyl-lower alkyl, in which the phenyl group may be substituted with halogen, lower alkyl or lower alkoxy; and R.sub.4 is hydrogen or alkyl. 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 the formula I.
本发明涉及以下式的新化合物:##STR1## 其中R.sub.1为氢、烷基或苯基-较低烷基,其中苯基可能被卤素、较低烷基或较低烷氧基取代;R.sub.2为烷基、烯基、炔基或苯基-较低烷基,其中苯基可能被卤素、较低烷基或较低烷氧基取代;R.sub.4为氢或烷基。此外,本发明还涉及制备式I化合物的方法,新的中间体,含有相同化合物的药物组合物,以及通过给予式I化合物的非毒性有效量来治疗由乙酰胆碱(AcCh)或肌碱系统功能障碍引起的疾病的方法。
