交联的聚(4-乙烯基吡啶)负载的叠氮化物离子是一种通用且可回收的聚合试剂,用于合成1-取代-1 H -1,2,3,4-四唑
摘要:
交联的聚(4-乙烯基吡啶)负载的叠氮化物离子[P 4 -VP] N 3易于制备,可用作合成1-取代-1 H -1,2,3,4-的有效聚合物试剂通过叠氮化物离子,伯芳族胺和原甲酸三乙酯在冰醋酸中的缩合反应生成四唑。在优化反应条件之后,还可以在非均相条件下使用[P 4 -VP] N 3对各种各样的伯芳族胺进行相应的1-芳基-1 H -1,2,3,4-四唑的制备。。在这种方法中,反应时间非常短,分离出的收率极高(90–98%)。1-芳基-1 H-1,2,3,4-四唑产物通过傅里叶变换红外(FT-IR)表征,其中一些还通过质子核磁共振(1 H NMR)谱表征,并将物理性质与文献值进行比较已知化合物。废聚合物试剂被定量再生,并重复使用数个循环而不会显着降低其活性。

An efficient, one-pot synthesis of multisubstituted 2-aminoquinolines from 1-aryl tetrazoles and internal alkynes has been developed. The reaction involves cyclization of 1-aryl tetrazoles with internal alkynes via rhodium(III)-catalyzed double C–H activation and copper(II)-mediated denitrogenation.
