process to prepare and fully characterize all possible stereoisomers of a drug candidate for biological evaluation. Despite many advances in asymmetric synthesis, developing general and practical strategies for obtaining all possible stereoisomers of an organic compound that has multiple contiguous stereocentres remains a challenge. Here, we report a stereodivergent copper-based approach for the expeditious

Copper‐catalyzed highly stereospecific hydroboration of internal allylic alcohols using a silyl ether transient protection strategy is reported. This in situ protection effectively avoids the preferential side reaction of free hydroxyl group with boron reagent, thus promoting hydroboration. This method provides both the anti‐ and the syn‐ diastereomers of 1,3‐diols in high level of diastereomeric ratios
