The present invention provides pyridine derivatives useful as intermediates of drugs and agricultural chemicals, electrophotographic receptors, dyes and so on. More specifically, the invention relates to novel pyridyltetrahydropyridines and novel pyridylpiperidines, and further to a method of manufacturing pyridine derivatives through reaction between bipyridine derivatives and benzyl halide or benzyloxycarbonyl halide and subsequent reduction of the resultant reaction products with the aid of palladium catalysts, platinum catalysts, ruthenium catalysts or rhodium catalysts.
本发明提供的吡啶衍生物可用作药物和农药、电致发光受体、染料等的中间体。更具体地说,本发明涉及新型吡啶四氢吡啶和新型吡啶哌啶,还涉及一种通过联吡啶衍生物与苄基卤化物或苄氧羰基卤化物反应,然后借助钯催化剂、铂催化剂、钌催化剂或铑催化剂还原反应产物来制造吡啶衍生物的方法。
