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.
本发明涉及一种新型
吡啶衍生物,其在
吡啶环的氮原子相邻处具有融合的5、6或7成员饱和碳氢环,并且在该碳氢环上有一个被分离一个碳原子的X基团,该基团X是
氰基、CONHR3、CSNHR3或CO2R5,其中R3选择氢、较低的烷基和较低的芳基烷基基团,R5选择氢、较低的烷基和较低的芳基烷基基团,这些基团可以被烷基、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CSNHR3的化合物是抗溃疡剂,其他化合物是其中间体。
