doubly nitrogenated two carbon building blocks. Here we report a gold-catalyzed oxidative functionalization of yndiamides to access unnatural amino acid derivatives, using a wide range of nucleophiles as a source of the amino acid side chain. The transformation proceeds under mild conditions, is highly functional group tolerant, and displays excellent regioselectivity through subtle steric differentiation
Yndiamides 是ynamides 的未开发表亲,作为双重氮化的两个碳构建块,提供了丰富的合成潜力。在这里,我们报告了使用各种亲核试剂作为氨基酸侧链来源的金催化氧化功能化炔二酰胺以获取非天然氨基酸衍生物。转化在温和条件下进行,具有高度的官能团耐受性,并通过炔二酰胺氮原子取代基的细微空间差异显示出优异的区域选择性。
