其中尤以胺烯加成反应(aza-Michael reaction)gl起了 人们更多的关注。因为胺基作为亲核试剂参与的迈克尔加成反应,除了具有上述 特点外,还具有其他类型迈克尔加成不具备的优...

Then we studied their aza-Michael reaction with imides, and found that triethylamine (TEA), triethylenediamine (DABCO) and quinine (10 mol%) could effectively catalyze the aza-Michael reaction of 4-nitrophthalimide to acrylaldehyde in acetonitrile. The yields reached to 97%, 79% and 92%, respectively.
随后我们对酰亚胺类化合物的氮杂Michael加成反应进行了研究,结果发现在乙腈作溶剂的条件下,三乙胺(TEA)、三乙烯二胺(DABCO)和奎宁(quinine)(10mol%)这三种叔胺类的有机小分子催化剂均能够有效地催化4-硝基邻苯二甲酰亚胺对丙烯醛的氮杂Michael加成,产率可以分别达到97%、79%和92%。
