A new method for the construction of 2-substituted and 2,2-disubstituted chromans via Pd-catalyzed carboetherification reactions between aryl/alkenyl halides and 2-(but-3-en-1-yl)phenols is described. These reactions effect formation of a C-O bond and a C-C bond to afford the chroman products in good yield, and also provide stereoselective access to tricyclic chroman derivatives.
描述了一种通过 Pd 催化芳基/烯基卤化物和 2-(but-3-en-1-yl) 苯酚之间的碳醚化反应构建 2-取代和 2,2-二取代色满的新方法。这些反应影响 CO 键和 CC 键的形成,以高产率提供色满产物,并且还提供立体选择性获取三环色满衍生物。
