A rapid, efficient, and metal-free Lewis acid-mediated methodology has been developed for the site-selective synthesis of unsymmetrical oxygenated biaryls. This simple and efficient methodology furnished highly oxygenated and functionalized unsymmetrical biaryls in good to excellent yields by the direct oxidative coupling of electron-rich arenes to the α-position of carbonyl functionality of in situ
已经开发出一种快速,有效且无金属的路易斯酸介导的方法,用于不对称氧化联芳基的位点选择性合成。这种简单有效的方法通过将富电子芳烃直接氧化偶联到原位生成的掩蔽苯醌的羰基官能团的α位上,从而使高氧和官能化的不对称联芳基具有良好的收率。
