A concise synthesis of di-O-methyl-β,γ-dehydrocurvularin, the di-O-methylated derivative of the naturally occurring nematicidal macrolide, β,γ-dehydrocurvuralin, was accomplished by starting from a commercially available aromatic carboxylic acid in a three-step sequence consisting of esterification, Friedel-Crafts acylation, and microwave-promoted ring-closing metathesis.
通过从市售的芳香羧酸开始,经过酯化、弗里德尔-克拉夫茨酰化和微波促进的环合复分解反应三个步骤,完成了对二-O-甲基-β,γ-脱氢曲古兰素(一种天然存在的杀线虫大环内酯β,γ-脱氢曲古兰素的二-O-甲基化衍生物)的简明合成。
