alkylation of an aldehyde using a chiral titanium sulfonamide complex and the cis double bond was installed using a Wittig reaction. This synthetic route was also applied to the preparation of structurally related analogs, which were used in structure–activity relationship studies for antibacterial activity.
已经建立了一种合成途径,即对溶血曼海姆氏菌和多杀性巴斯德氏菌有效的抗菌剂草酸1。使用手性钛磺酰胺络合物通过醛的催化不对称烷基化来控制仲羟基的绝对构型,并使用Wittig反应安装顺式双键。该合成途径还用于制备结构相关的类似物,这些类似物用于抗菌活性的构效关系研究中。
