中文摘要：

以苄基哌啶酮和苄胺为起始原料,经双Mannich反应、黄鸣龙还原和Pd/C脱苄基合成了双哌啶（4）。以无水碳酸钾为缚酸剂,丙酮为溶剂,4分别与氯乙酸乙酯、氯乙腈反应制得新型的双哌啶衍生物5和7;5经皂化反应水解为新的双哌啶衍生物（6）,其结构经UV-Vis,1H NMR和FT-IR表征。

英文摘要：

Bispidine（4） was synthesized from N-benzyl-4-piperidinone and benzyl amine by a three-step reaction of double Mannich,Wolff-Kishner,Pd/C catalyzed hydrogenation.Using postassium carbonate as the deacid agent and acetone as the solvent,two new bispidine derivatives（5 and 7） were synthesized by the reaction of 4 with ethyl chloroacetate and chloroacetonitrile,respectivily.Bispidine derivatives 6 was obtained by the saponification of 5.The structures were characterized by UV-Vis,1H NMR and FT-IR.
