Herein, nickel-catalyzed sustainable strategy for the synthesis of N-substituted pyrroles using butene-1,4-diols and butyne-1,4-diols with a series of aryl-, alkyl-, and heteroarylamines is reported. The catalytic protocol is tolerant of free alcohol, halide, alkyl, alkoxy, oxygen heterocycles, activated benzyl, and the pyridine moiety and resulted in up to 90% yield. Initial mechanistic studies involving
在本文中,报道了使用具有一系列芳基,烷基和杂芳基胺的丁烯-1,4-二醇和丁炔1,4-二醇,镍催化的可持续合成N-取代的吡咯的策略。催化方案可耐受游离醇,卤化物,烷基,烷氧基,氧杂环,活化的苄基和吡啶部分,并能产生高达90%的收率。最初的机理研究涉及确定的镍催化剂,速率的确定和反应顺序,包括氘标记实验,用于吡咯合成。
