醛、酮和亚胺的C=O和C=N键的单电子还原分别导致形成酮基和α-氨基烷基阴离子自由基。这些反应性中间体的特征在于相对于其母体分子的改变的电子特性,并经历各种各样的合成有用的转化,这是不可用于偶电子物种。本文综述了过渡金属光氧化还原催化下羰基衍生物生成酮基和α-氨基自由基的反应。我们主要集中在该领域的最新发展,以及给一个简短的概述催化对映选择性转化,提供手段,实现精确的立体控制离子自由基的反应性。
Single-electron reduction of C=O and C=N bonds of aldehydes, ketones, and imines results in the formation of ketyl and α-aminoalkyl anion radicals, respectively. These reactive intermediates are characterized by an altered electronic character with respect to their parent molecules and undergo a diverse range of synthetically useful transformations, which are not available to even-electron species. This Review summarizes the reactions of ketyl and α-aminyl radicals generated from carbonyl derivatives under transition-metal photoredox-catalysed conditions. We primarily focus on recent developments in the field, as well as give a brief overview of catalytic enantioselective transformations that provide means to achieve precise stereocontrol over the reactivity of ion radicals.
