copper-catalyzed N-arylation of pyrrole proceeded sequentially in a single flask to give N-arylated 3,4-disubstituted pyrroles smoothly. Thus, a series of desired N-arylated pyrroles were prepared directly from the electron-deficient alkenes.
通过使用吨丁醇钠和Cs 2 CO 3作为混合基,面包车Leusen吡咯合成和铜催化Ñ吡咯-arylation在单个烧瓶依次进行,得到Ñ -arylated 3,4-二取代的吡咯顺利。因此,直接从缺电子的烯烃制备了一系列所需的N-芳基吡咯。
