摘要:氧化白藜芦醇及其甲基化衍生物作为偶联前体的制备分为四个步骤,其中 Wittig 反应和随后的异构化反应是关键步骤.氧化白藜芦醇在各种氧化条件下的偶联反应产生了复杂且不可分离的偶联产物混合物.由辣根过氧化物酶-H2O2 或 Fecl3.6H2O 在丙酮系统中催化的甲基化氧化白藜芦醇的氧化二聚化分别主要产生 8-5-偶联和 8-10-偶联二氢苯并呋喃型二聚体.这种区域选择性仿生策略可能有助于合成其他二聚氧化白藜芦醇衍生物.

摘要:Alkoxy aromatic compounds are conveniently dealkylated to the corresponding phenolic compounds by treatment with aluminum chloride/N,N-dimethyl aniline complex. Aromatic poly O-demethylation is a unique feature of this invention. This process is applicable to the manufacture of polyphenols such as Resveratrol, Oxyresveratrol, Gnetol.

摘要:The invention discloses a series of resveratrol-derivative fluorescently labeled molecules and a synthesis method thereof. The fluorescently labeled molecules has a molecular formula as shown in formula (I). The synthesis method includes the steps of adding a certain amount of resveratrol derivative and solvent in a reaction vessel, adding a fluorescent marker as shown in formula (III) and a certain amount of alkali, reacting at 20° C.-60° C. for 2-10 hours, and after the reaction is completed, spin-drying the reaction solvent and performing post-processing to obtain the products.
