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.
本发明提供了吡啶衍生物,可用作药物和农业化学品,电子照相受体,染料等的中间体。更具体地说,本发明涉及新型吡啶基四氢吡啶和新型吡啶基哌啶,以及通过双吡啶衍生物和苯甲醰或苄氧羰基卤化物的反应制备吡啶衍生物的方法,并借助钯催化剂、铂催化剂、钌催化剂或铑催化剂还原所得反应产物的方法。
