  Irradiation of 9 leads to hydrogen abstraction by N(1) and fragmentation to 8 from a triplet with E τ ∼78 kcal/mol. Irradiation of 2-acylpyridines (10) leads to abstraction by both nitrogen and oxygen (cf. eq 4), with the same Stern-Volmer k q τ for the two processes

The principle of microscopic reversibility, which has previously rendered this strategy elusive, is overcome by a photoredox deprotonation through single electron transfer and subsequent hydrogen atom transfer (HAT). Specifically, the irradiation of racemic pyridylketones in the presence of a single photocatalyst and a tertiary amine provides nonracemic

  日期：——

  Asymmetric cross-dehydrogenative coupling (CDC) of C(sp3)–H bonds shows great potential for rapid and stereoselective construction of C–C bonds and use of molecular oxygen as the oxidant for such transformations is appealing in the context of green synthetic methodologies. However, the poor reactivity of oxygen at the ground state and the challenges in controlling the stereochemistry make it extremely

  C（sp 3）–H键的不对称交叉脱氢偶联（CDC）显示出快速且立体选择性地构建C–C键的巨大潜力，在绿色合成方法中，使用分子氧作为此类转化的氧化剂非常有吸引力。但是，基态氧的反应性差，控制立体化学的挑战使进入C（sp 3）-H前体的高对映选择性好氧CDC反应极为困难。在这里我们提出我们的努力实现这一目标通过铜基不对称光催化。手性铜催化剂通过分子氧引发可见光驱动的氧化CDC反应，并控制立体化学。以这种方式，已经实现了羰基化合物与x吨衍生物之间的非对映和对映选择性的交叉脱氢偶联。这项工作为立体选择性C–C键的形成提供了一种经济可行的方法，并证明了手性铜催化剂在困难的不对称光化学反应中的潜在应用。
