• A general N-alkylation platform via copper metallaphotoredox and silyl radical activation of alkyl halides
  作者：Nathan W. Dow、Albert Cabré、David W.C. MacMillan

  日期：2021.7

  The catalytic union of amides, sulfonamides, anilines, imines, or N-heterocycles with a broad spectrum of electronically and sterically diverse alkyl bromides has been achieved via a visible-light-induced metallaphotoredox platform. The use of a halogen abstraction-radical capture (HARC) mechanism allows for room temperature coupling of C(sp3)-bromides using simple Cu(II) salts, effectively bypassing

  通过可见光诱导的金属光氧化还原平台实现了酰胺、磺胺、苯胺、亚胺或N-杂环与广谱电子和空间多样化烷基溴的催化结合。卤素提取-自由基捕获 (HARC) 机制的使用允许使用简单的 Cu(II) 盐在室温下耦合 C( sp 3 )-溴化物，有效绕过通常与热诱导 S N 2 或 S相关的过高障碍N 1 N-烷基化。这种区域和化学选择性方案与 >10 类药物相关的N兼容- 亲核试剂，包括已建立的药剂，以及结构多样的伯、仲和叔烷基溴。此外，通过将N-亲核试剂与环丙基溴和未活化的烷基氯（与亲核取代途径不相容的底物）结合，突出了 HARC 方法与传统惰性偶联伙伴结合的能力。初步的机械实验验证了该平台的双重催化、开壳性质，这使得在传统的基于卤化物的N-烷基化系统中无法实现的反应性成为可能。
• Site-Selective C–H alkylation of Complex Arenes by a Two-Step Aryl Thianthrenation-Reductive Alkylation Sequence
  作者：Beatrice Lansbergen、Paola Granatino、Tobias Ritter

  DOI：10.1021/jacs.1c03459

  日期：2021.6.2

  undirected para-selective two-step C–H alkylation of complex arenes useful for late-stage functionalization. The combination of a site-selective C–H thianthrenation with palladium-catalyzed reductive electrophile cross-coupling grants access to a diverse range of synthetically useful alkylated arenes which cannot be accessed otherwise with comparable selectivity, diversity, and practicality. The robustness

  在此，我们提出了复杂芳烃的非定向对位选择性两步C-H烷基化，可用于后期功能化。位点选择性 C-H 噻蒽醌化与钯催化的还原亲电试剂交叉偶联相结合，可以得到多种合成上有用的烷基化芳烃，而这些烷基化芳烃是无法以其他方式获得的，具有相当的选择性、多样性和实用性。两个复杂片段的基于铊的还原偶联进一步证明了这种转化的稳健性。
