A general procedure for the Michael addition of pyrroles with electron-deficient olefins using silica gel supported reagent under microwave irradiation, has been developed. This new method is fast, efficient, environmentally benign and solvent-free. A catalytic amount of BiCl 3 is employed for moderately bulk electron-deficient olefins.
已经开发了在微波辐射下使用硅胶支持的试剂将吡咯与缺电子烯烃迈克尔加成的一般程序。这种新方法快速、高效、环保且无溶剂。催化量的 BiCl 3 用于中等体积的缺电子烯烃。
