Oseltamivir phosphate (Tamiflu) has been synthesized from cis-2,3-bis(hydroxymethyl)aziridine. After protection of the cis-2,3-bis(hydroxymethyl)aziridine with a Boc group, desymmetrization provided a chiral aziridine, which was a key intermediate to install the required stereogenic center containing a nitrogen atom. Allylation and ring closing metathesis are the key reactions to obtain the cyclic
磷酸奥司他韦(Tamiflu)是由顺式-2,3-双(羟甲基)氮丙啶合成的。在用Boc基团保护顺式-2,3-双(羟甲基)氮丙啶后,脱对称反应提供了手性氮丙啶,这是安装所需的含氮原子的立体异构中心的关键中间体。烯丙基化和闭环复分解是获得成功转化为所需磷酸奥司他韦的环状产物的关键反应。
