protecting-group-free route to (−)-taiwaniaquinone F based on a ring contraction and subsequent aromatic oxidation of a sugiol derivative is reported. In addition, the first synthesis of (+)-taiwaniaquinol A is reported via short time exposure of (−)-taiwaniaquinone F to sunlight triggering a remote C–H functionalization. The hypothesis that the biogenesis of some methylenedioxy bridged natural products could
据报道,基于杉基醇衍生物的环收缩和随后的芳族氧化,到(-)-台湾硫醌F的无保护基的途径。此外,据报道,(+)-台湾紫醌A的第一个合成是通过将(-)-台湾紫醌F短时间暴露在阳光下引发的远程CH-H功能化而实现的。提出了一些假说,一些亚甲二氧基桥接的天然产物的生物发生可以通过类似的非酶机制进行。
