well‐developed and growing body of work in Cu catalysis, the potential of Cu to serve as a photocatalyst remains underexplored. Reported herein is the first example of visible‐light‐induced Cu‐catalyzed decarboxylative C(sp3)−H alkylation of glycine for preparing α‐alkylated unnatural α‐amino acids. It merits mentioning that the mild conditions and the good functional‐group tolerance allow the modification
尽管
铜催化方面的工作已经发展成熟并且在不断发展,但是
铜作为光催化剂的潜力仍未得到开发。本文报道的是第一个可见光诱导的
铜催化甘
氨酸脱羧C(sp 3)-H烷基化制备甘
氨酸α-烷基化非天然
α-氨基酸的例子。值得一提的是,温和的条件和良好的官能团耐受性允许使用此方法对肽进行修饰。机理研究表明,该反应涉及自由基-自由基偶联途径。
