versatile oxidative coupling reaction was developed for the synthesis of valuable β‐functionalized unsaturated ketones and meta‐substituted phenols. In the case of intramolecular reactions, achieving rapid molecular complexity through multiple dehydrogenative couplings is already a well‐established strategy. Herein, we report an intermolecular multiple dehydrogenative coupling between ketones and nucleophilic
开发了一种有效且通用的氧化偶联反应,用于合成有价值的β-官能化不饱和酮和间位取代的苯酚。在分子内反应的情况下,通过多次脱氢偶联实现快速的分子复杂性已经是一种行之有效的策略。在这里,我们报告了使用廉价的氧化铜(I)作为催化剂,酮与亲核胺或硼酸之间的分子间多重脱氢偶联。该方法可轻松获得高度理想的化学产品,例如α,β-不饱和酮,烯胺酮和合成相关的间位取代的苯酚。
