由3,5-二甲基谷氨酸(DMOA)和法尼基焦磷酸衍生的化合物的合成途径尚未见报道,尽管具有广泛的生物合成和药用价值。在这里,我们报道了首次通过13个步骤全合成伯克利酮A,这是一种潜在的通向大量真菌衍生的分枝萜类化合物的通道化合物。此外,我们还进一步开发了一种新的环化反应,用于一步合成羟基1,3-环己二酮。
Synthetic pathways to complex meroterpenes derived from 3,5-dimethylorsellinic acid (DMOA) and farnesyl pyrophosphate have not been reported despite heavy biosynthetic and medicinal interest. Herein we report the first total synthesis of berkeleyone A, a potential gateway compound to a plethora of fungal derived meroterpenes, in 13 steps. In addition, we have further developed a novel annulation reaction for the synthesis of hydroxylated 1,3-cyclohexadiones in a single step.
