diazoacetates with cysteine residues that enabled metal‐free, S−H functionalization under visible‐light conditions. Moreover, this process could be intensified by a continuous‐flow photomicroreactor on the acceleration of the reaction (6.5 min residence time). The batch and flow protocols described were applied to obtain a wide range of functionalized cysteine derivatives and cysteine‐containing dipeptides
我们描述了芳基重氮乙酸酯与半胱氨酸残基的S-H键插入反应的应用,该反应可在可见光条件下实现无金属的S-H功能化。此外,连续反应光微反应器可加快反应速度(6.5分钟的停留时间),从而增强该过程。所描述的批次和流程方案可用于获得各种功能化的半胱氨酸衍生物和含半胱氨酸的二肽,从而为其在温和条件下的功能化提供了一个简单而通用的平台。
