A concise and stereocontrolled synthesis of rosuvastatin calcium has been accomplished, with the key steps including a Keck enantioselective allylation of chloroacetaldehyde with allyltributylstannane to install 5R-stereocenter and a VO(acac)2-catalyzed syn-diastereoselective epoxidation of (S)-1-chloropent-4-en-2-ol to set the requisite 3R-chirality.
罗苏伐他汀钙的简明和立体控制合成已经完成,关键步骤包括氯乙醛与烯丙基三丁基锡烷的Keck对映选择性烯丙基化以安装5 R-立体中心和VO(acac)2-催化的(S)-1的顺-非对映选择性环氧化-chloropent-4-en-2-ol设置必要的3 R手性。
