A short and efficient synthesis of (+)-spirolaxine methyl ether, a metabolite of the fungus Sporotrichum laxum with inhibitory activity against Helicobacter pylori, is described. The synthesis has been carried out by a Prins cyclization, to obtain the [6,5]-spiroketal system, and a Wadsworth−Emmons condensation, applied for the installation of the polymethylene chain on the phthalide moiety.
描述了一种短而有效的合成(+)-螺菌灵甲基醚的方法,该化合物是具有抑制幽门螺杆菌活性的真菌Sporotrichum laxum的代谢产物。合成已通过Prins环化进行,以获得[6,5]-螺酮系统和Wadsworth-Emmons缩合,用于在邻苯二甲酸酯部分上安装多亚甲基链。
