for the synthesis of aryl amides via oxidative copper-catalyzed coupling of commercially available aryl boronic acids and bench stable Nα-protected amino-acid azides is reported. The potential utility of this protocol is demonstrated through a survey of diversely substituted aryl boronic acids and several side-chain functionalized amino-acid azides, leading to the preparation of the desired amidated
摘要 报道了一种通过氧化铜催化偶联市售芳基硼酸和实验室稳定的 Nα 保护的氨基酸叠氮化物合成芳基酰胺的简单有效方法。通过对不同取代的芳基硼酸和几种侧链官能化氨基酸叠氮化物的调查,证明了该协议的潜在效用,从而以良好到优异的产率制备所需的酰胺化产品。这种酰胺合成适用于制备不能或难以通过经典方法获得的酰胺(如肽芳基酰胺和空间位阻氨基酸)。图形概要
