approach for the activation of esters via a radical-mediated process enabled by a copper/Selectfluor system. A variety of para-methoxybenzyl esters derived from bulky carboxylic acids and amino acids can be easily converted into the corresponding acyl fluorides, directly used in the one-pot synthesis of amides and peptides. As a proof of concept, this method was applied to the iterative formation of sterically
在本文中,我们描述了一种通过铜/ Selectfluor系统实现的自由基介导的过程来活化酯的新方法。衍生自庞大的羧酸和氨基酸的多种对甲氧基苄基酯可轻松转化为相应的酰基氟,直接用于酰胺和多肽的一锅法合成中。作为概念的证明,该方法被应用于空间位阻酰胺键的迭代形成。
