A copper-catalyzed reductive cross-coupling reaction of nonactivated alkyl tosylates and mesylates with alkyl and aryl bromides was developed. It provides a practical method for efficient and cost-effective construction of aryl-alkyl and alkyl-alkyl CC bonds with stereocontrol from readily available substrates. When used in an intramolecular fashion, the reaction enables convenient access to various substituted carbo- or heterocycles, such as 2,3-dihydrobenzofuran and benzochromene derivatives.
开发了一种铜催化的未活化甲苯磺酸酯和甲磺酸酯与烷基和芳基溴的还原交叉偶联反应。它提供了一种实用的方法，可从容易获得的底物高效且经济地构建具有立体控制的芳基 - 烷基和烷基 - 烷基CC键。当以分子内方式使用时，该反应能够方便地获得各种取代的碳环或杂环，例如2,3 - 二氢苯并呋喃和苯并色烯衍生物。
