A copper‐catalyzed asymmetric allylic boronation (AAB) gives access to syn‐ and anti‐1,2‐diols. The method facilitates an iterative strategy for the preparation of polyols (see scheme), such as the fully differentiated L‐ribo‐tetrol and protected D‐arabino‐tetrol. P=protecting group
铜催化的不对称烯丙基硼化(AAB)使人们可以合成顺式和反式1,2-二醇。该方法便于迭代策略多元醇(参见方案),如完全分化的制备大号-ribo-四醇和保护d -arabino-四醇。P =保护基
