Minisci-type alkylation of electron-deficient heteroarenes has been a pivotal technique for medicinal chemists in the synthesis of drug-like molecules. However, such transformations usually require harsh conditions (e.g., strong acids, stoichiometric amount of oxidants, elevated temperatures, etc.). Herein, by utilizing photoredox catalysis, a highly-selective alkylation method using heteroaryl sulfones
电子缺陷型杂芳烃的Minisci型烷基化已成为药物化学家合成类药物分子的关键技术。但是,这种转化通常需要苛刻的条件(例如强酸,化学计量的氧化剂,高温等)。本文中,通过利用光氧化还原催化,已经开发了使用杂芳基砜的高选择性烷基化方法,其可以在无酸和氧化还原中性条件下进行。由于这些温和的条件,可以安装具有挑战性但又优先的结构,例如单糖和未保护的仲胺。
