Functionalized heteroaromatic amines are readily prepared by the oxidative coupling of polyfunctional zinc amidocuprates using PhI(OAc)2 as oxidant. Various sensitive heterocyclic organometallics undergo this oxidative cross-coupling reaction furnishing aminated heteroaromatics. A high functional group tolerance and relative insensibility to steric hindrance characterize this general amination reaction
通过使用PhI(OAc)2作为氧化剂,通过多官能氨基cup酸锌的氧化偶联,可以轻松制备官能化的杂芳族胺。各种敏感的杂环有机金属会经历这种氧化交叉偶联反应,从而提供胺化的杂芳族化合物。较高的官能团耐受性和对空间位阻的相对敏感性是这种一般胺化反应的特征。描述了一种制备受保护的伯和仲以及叔杂芳基胺的实用程序。 胺化-酰胺基铜酸盐-CN键形成-酰胺化锂-多官能锌试剂
