The invention relates to novel pyridine derivatives which have a fused 5,6, or 7-membered saturated hydrocarbon ring adjacent to the nitrogen of the pyridine ring, and a group X situated on said hydrocarbon ring and separated by one carbon atom from the pyridine nitrogen atom, said group X is cyano, CONHR.sup.3, CSNHR.sup.3 or CO.sub.2 R.sup.5 wherein R.sup.3 is selected from hydrogen, lower alkyl and lower aralkyl radicals and R.sup.5 is selected from hydrogen, lower alkyl and lower aralkyl radicals which may be substituted by alkyl, alkoxy, halogen, nitro or trifluoromethyl; other substituents may be present. Compounds wherein X is CSNHR.sup.3 are anti-ulcer agents and the other compounds are intermediates therefor.
该发明涉及具有与吡啶环的氮相邻的融合的5、6或7成员饱和碳氢环的新型吡啶衍生物,以及位于所述碳氢环上并且与吡啶氮原子相隔一个碳原子的基团X,所述基团X为氰基、CONHR.sup.3、CSNHR.sup.3或CO.sub.2R.sup.5,其中R.sup.3从氢、较低的烷基和较低的芳基烷基基团中选择,R.sup.5从氢、较低的烷基和较低的芳基烷基基团中选择,可以被烷基、烷氧基、卤素、硝基或三氟甲基取代;其他取代基也可以存在。其中X为CSNHR.sup.3的化合物是抗溃疡剂,其他化合物是其中间体。
