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
SRR- Ezetimibe 2和RSS -Ezetimibe 3这两种立体异构体是胆固醇吸收抑制剂药物Ezetimibe 1的相关物质。在此,我们提出了一种高效,实用的合成方法来提供这些两种立体异构体,第一次,和的证明SRR -Ezetimibe 2通过单晶X-射线分析。我们的研究将为有机化学家研究Ezetimibe 1的杂质分布提供巨大帮助。
