In the frame: A cascade sequence combining an asymmetric Henry reaction and a stereoselective intramolecular iodocyclization provides direct access to an enantioenriched tricyclic hexahydrochromeno[4,3‐b]pyrrole framework (see scheme). The Henry reaction is catalyzed by copper in the presence of L1.
在框架中:级联序列结合了不对称的亨利反应和立体选择性的分子内碘环化作用,可直接进入对映体富集的三环六氢色素[4,3- b ]吡咯骨架(参见方案)。在L1存在下铜催化了亨利反应。
