Paulownin on treatment with triethylsilane and BF3-etherate reacts in a similar manner to gmelinol, giving an aryltetralin as the product. In contrast, wodeshiol under the same conditions rearranges to two isomeric tetrahydropyran derivatives, the structures of which have been deduced on the basis of their 1H and 13C n.m.r. spectra, including NOE and spin decoupling experiments.
用三乙基硅烷和BF 3-醚酸酯处理的泡桐素的反应方式与醇二甲酚相似,得到芳基四氢萘为产物。相比之下,沃得舒醇在相同条件下重排为两种异构的四氢吡喃衍生物,其结构是根据其1 H和13 C nmr光谱推导的,包括NOE和自旋解偶联实验。
