A novel cobalt-catalyzed carbonylative coupling of ethers with amines to construct α-carbonylated ethers has been achieved. Alfuzosin, a medicine for treatment of benign prostatic hyperplasia (BPH), can be synthesized by this process straightforwardly.

A metal-free silyl-pyridylation of alkenes using silyl boronates and B2pin2 through a pyridine-mediated B-interelement activation has been demonstrated, which provides a practical strategy for a variety of C4-silylalkylated pyridines. DFT calculations and control experiments show that the reaction proceeds through a silyl radical addition/radical–radicalcoupling sequence. This protocol features a
已经证明了使用甲硅烷基硼酸盐和 B 2 pin 2通过吡啶介导的 B 元素间活化对烯烃进行无金属甲硅烷基吡啶基化,这为各种 C 4甲硅烷基烷基化吡啶提供了实用的策略。DFT 计算和控制实验表明,反应通过甲硅烷基自由基加成/自由基-自由基偶联顺序进行。该协议具有广泛的底物范围和优异的官能团兼容性,因此在生物活性分子的后期修饰中展示了巨大的潜力。
