When guaiol was dehydrated with such reagents as thionyl chloride-pyridine, phosphorus oxychloride-pyridine or potassium bisulphate, the isopropenyl derivative (IIa) was always obtained as a main product, together with a small amount of IIb. Catalytic reduction of IIa in alkaline media afforded α-dihydroguaiene (V), while in neutral or acid media it gave a mixture of V and its double bond isomer (VI)
当将愈创木酚用亚硫酰氯-吡啶,氧氯化磷-吡啶或硫酸氢钾等试剂脱水时,总是得到异丙烯基衍生物(IIa)和少量IIb作为主要产物。在碱性介质中催化还原IIa可获得α-二氢胍(V),而在中性或酸性介质中则得到V及其双键异构体(VI)的混合物。
