The synthesis of 1-butylpyrrolidine and its derivatives (1-butylpyrrolidine with a little of 1-butenylpyrrolidines) was developed via a one-pot method from ammonia and 1,4-butandiol. Here, the product of 1-butylpyrrolidine was emphatically investigated, and the yield was 76% under the optimized conditions. Such a route was realized through successive N-alkylation using aqueous ammonia as the nitrogen source over the CuNiPd/ZSM-5 catalyst, which was prepared by a simple incipient wetness method. In this route, 1,4-butandiol not only participated in the formation of the N-heterocycle, but also acted as an alkylating reagent. This work offers a straightforward, economical route for 1-butylpyrrolidine and its derivatives.

在CuNiPd / ZSM-5催化剂上由氨水和1,4-丁二醇一锅法合成1-丁基吡咯烷及其衍生物

通过一锅法从氨和1,4-丁二醇开发了1-丁基吡咯烷及其衍生物（1-丁基吡咯烷和少量1-丁烯基吡咯烷）的合成方法。在此，着重研究了1-丁基吡咯烷的产物，在最佳条件下产率为76％。通过使用氨水作为氮源在CuNiPd / ZSM-5催化剂上连续N-烷基化来实现这种途径，该CuNiPd / ZSM-5催化剂是通过简单的初湿法制备的。在这种途径中，1，4-丁二醇不仅参与了N-杂环的形成，而且还充当了烷基化试剂。这项工作为1-丁基吡咯烷及其衍生物提供了一种简单，经济的途径。
