摘要：
Oxidation of espintanol by silver oxide gives trimeric monoterpenoid (+/-)-schefflone via ortho-quinone methide intermediate. The heating of 6-[(dibenzylamino)methyl]-3-isopropyl-2,4-dimethoxyphenol also results in ortho-quinone methide intermediate which is trapped by 3-(dimethylamino)-5,5-dimethylcyclohex-2-en-1-one or benzotriazole.
