Four generations of chemoenzymatic approaches to oseltamivir are presented. The first two generations relied on the use of cyclohexadiene-cis-diol derived enzymatically from bromobenzene. The third and fourth generation used the corresponding diol obtained from ethyl benzoate by fermentation with E. coli JM109(pDTG601a). Oseltamivir was obtained from ethyl benzoate by intersecting intermediate 39 (third-generation
介绍了四代奥司他韦的化学酶法。前两代依靠酶法衍生自溴苯的环己二烯-顺-二醇的使用。第三和第四代使用通过与大肠杆菌JM109(pDTG601a)发酵从苯甲酸乙酯获得的相应二醇。通过将中间体39(第三代合成物)和中间体45相交,从苯甲酸乙酯获得Oseltamivir(第四代合成)。这两种先进的方法都受益于对称性的考虑和丙烯酸酯双键的易位以及随之而来的C-1羟基的消除。通过使用效率指标评估合成的整体效率,并将其与奥司他韦的其他合成(学术和工业)进行比较。
