Two named reactions of fundamental importance and paramount utility in organic synthesis have been reinvestigated, the Barton decarboxylation and Giese radical conjugate addition. N‐hydroxyphthalimide (NHPI) based redox‐active esters were found to be convenient starting materials for simple, thermal, Ni‐catalyzed radical formation and subsequent trapping with either a hydrogen atom source (PhSiH3)
已经重新研究了有机合成中两个具有根本重要性和最重要实用性的反应,即巴顿脱羧反应和吉斯自由基共轭加成反应。人们发现基于N-羟基邻苯二甲酰亚胺 (NHPI) 的氧化还原活性酯是简单、热、Ni 催化自由基形成以及随后用氢原子源 (PhSiH 3 ) 或缺电子烯烃捕获的方便起始材料。这些反应具有操作简单、试剂便宜和范围扩大的特点,肽化学领域的例子证明了这一点。
