Copper‐catalyzed reaction of aryl isocyanides with active methylene isocyanides and arylsulfonothioates is developed for the synthesis of sulfur‐containing trisubstituted imidazoles. This reaction not only forms new C−C, C−N, and C−S bonds in one step, but also provides a new strategy for the construction of trisubstituted imidazoles based on the isocyanide‐isocyanide [3+2] cycloaddition.
开发了一种铜催化的芳基异氰化物与活性亚甲基异氰化物和芳基磺基硫代酸酯的反应,用于合成含硫三取代的咪唑。该反应不仅一步一步就形成了新的CC,CN和CS键,而且为基于异氰酸酯-异氰酸酯[3 + 2]环加成反应的三取代咪唑的构建提供了新的策略。
