Taking the strain: The asymmetric total synthesis and stereochemicalassignment of (−)‐cavicularin, which features a highly strained polycyclophane ring system, has been achieved. The key features of this synthesis are 1) macrocyclization by an SNAr reaction, 2) group‐selective reaction to induce planar chirality in a highly stereoselective manner, and 3) radical transannulation to construct the highly
承受应变:(-)-cavicularin的不对称全合成和立体化学分配已实现,该结构具有高度应变的多环烷环系统。该合成的关键特征是:1)通过S N Ar反应进行大环化; 2)以高度立体选择性的方式诱导平面手性的基团选择性反应; 3)自由基转环作用以构建高度应变的环系统。
