Total synthesis of IKD-8344 was accomplished via stepwise cyclodimerization of the monomeric seco acid under Yamaguchi conditions. In the synthesis of the monomeric seco acid, Wittig olefination reaction was employed for an efficient bond formation at C7–C8. The threo-trans oxolane unit for the rings a and c was prepared via intramolecular Williamson ether synthesis of the hydroxyl mesylate prepared
IKD-8344的全合成是通过在Yamaguchi条件下对单体癸二酸进行逐步环二聚而完成的。在单体癸二酸的合成中,Wittig烯烃化反应用于在C7–C8处形成有效的键。通过不对称醛醇缩合反应制得的甲磺酸羟基的分子内威廉森醚合成,制备环a和c的苏-反式环氧丙烷单元。β-烷氧基甲基丙烯酸酯中间体的自由基环化为b环片段提供了苏-顺式环氧丙烷单元。
