The structures of hydroxyeremophilone and its various derivatives have been verified using NMR spectroscopy. All four of the thermodynamically stable C-8 and C-9 eremophilanones have now been prepared and their optical rotatory dispersion curves and NMR spectra compared. Three of these ketones have been prepared from the naturally occurring hydroxyeremophilone by variation of the experimental conditions
使用核磁共振波谱法已经证实了羟乙双氢马酮及其各种衍生物的结构。现在已经制备了全部四个热力学稳定的C-8和C-9嗜铁二酮,并比较了它们的旋光色散曲线和NMR光谱。这些酮中的三种是通过改变实验条件从天然存在的羟乙二酮制备的。第四种稳定的酮是由密切相关的倍半萜类艾美罗酮和羟基二氢艾美罗酮制备的。通过用碱处理和通过氢化,然后分别与三氧化二铋反应,将羟基二氢古铜酮转化为两种二酚A和B。用碱将不稳定的二酚-B转化为稳定的二酚-A。
