  摘要：

  仍然明显缺乏开发能以选择性，实用，低成本和环境友好的模式快速构建复杂的有机硼酸酯的稳健策略。在这里，我们通过仅使用由新戊酰基引导的BBr 3避免了使用任何金属，为吡咯的位点选择性CH硼化开发了一种通用策略。通常，位点选择性主要受螯合和电子效应的影响，因此形成了多种C2硼化的吡咯，以抵抗空间效应。成型产品可以很容易地参与下游转型，从而实现了逐步经济的过程来获得立普妥（Lipitor）等药物。DFT计算（wB97X-D）证明了该反应的首选位置选择性。

  摘要：

  研究了一系列N-磺酰基-2,5-二氢-3-取代吡咯在分子内Heck反应中的区域选择性。这些衬底在新杂环形成的环尺寸方面没有偏见。结果表明，在一定条件下观察到了很高的区域选择性，并且在烯烃最受阻的末端存在潜在的碳-碳键形成趋势。对于两个示例（3 Me和3 t Bu），进行了DFT计算，结果表明，在这两种情况下，对于碳酸盐的建模过渡态，对于实验上优选的异构体，在能量上都较低。

  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

  highly selective C-2 difluoromethylation of indole derivatives was developed by using sodium difluoromethylsulfinate (HCF2SO2Na) as the source of difluoromethyl groups and a Cu(II) complex as the catalyst. Various substrates were well tolerated in this transformation and the desired products were obtained in moderate to good yields. Moreover, the late-stage C-2 difluoromethylation of bioactive molecules
