indispensable building blocks for modern synthetic chemistry. In recent years, visible light photoredox catalysis has become a promising avenue to access C-centered radicals from a broad array of latent functional groups, including boronic acids. Herein, we present an aqueous protocol wherein water features a starring role to help transform aliphatic, aromatic, and heteroaromatic boronic acids to C-centered
以碳为中心的自由基是现代合成化学必不可少的组成部分。近年来,可见光光氧化还原催化已成为从包括硼酸在内的广泛的潜在官能团中进入以C为中心的自由基的有前途的途径。在本文中,我们介绍了一种水性方案,其中水起着星形作用,以帮助将脂族,芳族和杂芳族硼酸转化为C具有生物启发性的黄素光催化剂的中心自由基。这些自由基通过开壳共轭物加成到不同的Michael受体上,以递送各种不同的烷基化产物,包括三种药学上相关的化合物。通过计算研究,氘标记,自由基捕获实验和光谱分析研究了反应机理。
