(+)-Goniodiol 7 and (+)-9-deoxygoniopypyrone 8, belonging to the group of styryllactones, have been synthesized in five steps and 75% yield respectively from C4-esters 1a and 1b. The key step of these syntheses is a triflate-sulfone coupling which allowed a rapid construction of the backbone of the title compounds as well as the efficient installation of a masked Z-acrylate moiety.
属于苯乙烯基内酯类的(+)-壬二醇7和(+)-9-脱氧goniopypyrone 8分别从C 4-酯1a和1b以五个步骤合成,产率为75%。这些合成的关键步骤是三氟甲磺酸酯-砜偶联,其允许快速构建标题化合物的骨架以及有效安装掩蔽的Z-丙烯酸酯部分。
