bioactive molecules and pharmaceuticals. Therefore, there is great interest in developing a chemoselective alkylation of heteroarenes under mild conditions, particularly during a late-stage functionalization step for the purpose of rapid derivatization. Herein, we introduce an efficient visible-light-promoted C–H alkylation of nitrogen-containing heteroarenes by using C4-alkyl 1,4-dihydropyridines (DHPs) as
烷基化的杂
芳烃广泛存在于
生物活性分子和药物中。因此,在温和的条件下,特别是在为了快速衍生化的后期官能化步骤期间,开发杂
芳烃的
化学选择性烷基化引起了极大的兴趣。本文中,我们通过在环境温度下使用C4-烷基1,4-
二氢吡啶(
DHP)作为自由基前体,引入了一种有效的可见光促进含氮杂
芳烃的CH烷基化反应。通过使用各种C4-烷基
DHP,可以成功地烷基化各种杂
