A highly efficient method for the oxidative coupling of 2‐substituted 3‐oxindoles with aromatic compounds to form 2,2‐disubstituted indolin‐3‐ones with broad scope is described. This work utilized oxygen as the terminal oxidant and a base‐metal catalyst under mild conditions instead of toxic/precious‐metal reagents and higher‐molecular‐weight oxidants. Quaternary structures were produced in modest‐to‐excellent
描述了一种高效的方法,用于2-取代的3-氧吲哚与芳族化合物的氧化偶联,形成具有广泛应用范围的2,2-二取代的吲哚-3-酮。这项工作在温和的条件下利用氧气作为末端氧化剂和贱金属催化剂,而不是使用有毒/贵金属试剂和更高分子量的氧化剂。无需预功能化,即可以中等至出色的产率(高达96%)生产四级结构。
