benzylic amines with phenols has been achieved to provide biaryl ethers that are prevalent in biologically active compounds. A variety of substitution patterns on the aryl boronate ester and the phenol are tolerated under the reaction conditions, providing moderate to high yields. A competition reaction between phenol and aniline revealed condition-dependent selectivity in which the phenol could be highly
已经实现了邻苯甲酰化苄基胺与苯酚的铜催化醚化,以提供在生物活性化合物中普遍存在的联芳醚。在反应条件下,可以耐受芳基硼酸酯和苯酚上的多种取代方式,从而提供中等至高收率。苯酚和苯胺之间的竞争反应显示了条件依赖性的选择性,其中苯酚可能比苯胺更受青睐。
