through nine and ten steps, respectively. The key transformation for the synthesis of amorfrutin A was the Claisen rearrangement of a mono-O-(1,1-dimethylallyl)resorcinol derivative to install the C3-prenyl substituent, while that for the synthesis of amorfrutin C was the double Claisen rearrangement of a di-O-(1,1-dimethylallyl)resorcinol derivative to introduce the two prenyl groups at the C3 and C5
从38%的市售3,5-二甲氧基苯甲醛中获得了两个烯丙基化的芳香族聚酮化合物amorfrutins A和C的简明统一的全合成物,它们显示出各种医学上重要的生物学特性,例如抗微生物剂,PPARγ调节剂和群体感应抑制活性。通过9个步骤和10个步骤分别获得10%的总收益。合成阿莫frutin A的关键转化是单-O-(1,1-二甲基烯丙基)间苯二酚衍生物的Claisen重排以安装C3-异戊烯基取代基,而合成Amorfrutin C的关键转化是C-sensen的双重Claisen重排。二-O-(1,1-二甲基烯丙基)间苯二酚衍生物,可同时在C3和C5位置引入两个异戊烯基。
