form of clavatol, ortho-quinone methide, can be generated from hydroxyclavatol in an aqueous system and used as a highly reactive intermediate for coupling with diverse natural products under very mild conditions. These include flavonoids, hydroxynaphthalenes, coumarins, xanthones, anthraquinones, phloroglucinols, phenolic acids, indole derivatives, tyrosine analogues, and quinolines. The clavatol moiety
克拉维醇的活性形式,邻醌甲基化物,可以在水性系统中由羟基克拉维醇产生,并用作在非常温和的条件下与各种天然产物偶联的高反应性中间体。这些包括类黄酮,羟基萘,香豆素,氧杂蒽酮,蒽醌,间苯三酚,酚酸,吲哚衍生物,酪氨酸类似物和喹啉。克拉法醇部分主要通过CC键与酚羟基/氨基的邻位或对位以及吲哚环的C2位相连。
