were synthesized in 20-88% yields by the reaction of aniline and aniline derivatives with 1,4-butane- and 1,5-pentanediols in the presence of Fe- containing catalysts and carbon tetrachloride. 1,4-Butane- and 1,5-pentanediols are partially chlorinated under the reaction conditions to give chlorohydrins, which subsequently undergo N- heterocyclization with anilines to give N-arylpyrrolidines and N-arylpiperidines
在含铁催化剂和四氯化碳存在下,通过苯胺和苯胺衍生物与 1,4-丁烷和 1,5-戊二醇反应合成 N-芳基吡咯烷和 N-芳基哌啶,产率 20-88%。1,4-丁烷-和1,5-戊二醇在反应条件下部分氯化得到氯醇,随后与苯胺进行N-杂环化得到N-芳基吡咯烷和N-芳基哌啶。
