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
研究了未活化的烷基甲苯磺酸盐和甲磺酸盐与烷基和芳基溴化物的铜催化还原性交叉偶联反应。它提供了一种可行的方法,可通过易于获得的底物进行立体控制,从而高效,经济地构建芳基-烷基和烷基-烷基CC键。当以分子内方式使用时,该反应可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。
