cholesterol absorption inhibitor Ezetimibe 1, the formation of several stereoisomers was observed. To study the complete stereoisomer profile of Ezetimibe 1, we have synthesized and completely characterized several key stereoisomers of Ezetimibe 1 for the first time. This study will provide an access to the reference standard of these stereoisomers and may have some implications in the development of new medicines

led to less-active compounds; however, modifications at the 1' position provided compounds with improved cholesterol absorption inhibitory activity. An enantioselective route for the synthesis of C3 1'-sulfur-substituted azetidinones and the development of structure-activity relationships for this series of compounds are presented.

The two stereoisomers, SRR-Ezetimibe 2 and RSS-Ezetimibe 3 are related substances of the cholesterol absorption inhibitor drug Ezetimibe 1. Herein, we present an efficient and practical synthesis approach to deliver these two stereoisomers for the first time, and a proof of SRR-Ezetimibe 2 by single-crystal X-ray analysis. Our research will be of immense help for organic chemists to study the impurity
