Rh-Catalyzed Highly Enantioselective Synthesis of Aliphatic Sulfonyl Fluorides
iScience, 2019 Summary: Rh-catalyzed, highly enantioselective (up to 99.8% ee) synthesis of aliphatic sulfonyl fluorides was accomplished. This protocol provides a portal to a class of novel 2-aryl substituted chiral sulfonyl fluorides, which are otherwise extremely ...
