the most useful tools for synthesizing various N-heterocyclic compounds, the highly chemoselective deoxygenation of densely functionalized N-heterocyclic N-oxides has received much attention from the synthetic chemistry community. Here, we provide a protocol for the highly chemoselective deoxygenation of various functionalized N-oxides under visible light-mediated photoredox conditions with Na2-eosin
由于它们的位点选择性C–H官能化现在被认为是合成各种N-
杂环化合物的最有用的工具之一,因此稠密官能化的N-杂环N-氧化物的高度
化学选择性脱氧受到了合成
化学界的广泛关注。在这里,我们提供了一种在Na 2-
曙红Y作为有机光催化剂的情况下,在可见光介导的光氧化还原条件下,对各种功能化N-氧化物进行高度
化学选择性脱氧的方案。机理研究表明,有机光催化剂的激发态被Hantzsch酯还原性淬灭。这种操作简单的技术可耐受各种官能团,并允许高产率,数克级的脱氧。
