Aryloxyacetamides Derived from Resveratroloside and Pinostilbenoside
摘要:
Etherification of phenolic hydroxyl groups of resveratroloside and pinostilbenoside (natural 3,4',5-trihydroxystilbene derivatives) with methyl bromoacetate afforded compounds ArOCH2CO2Me, which on treatment with amines produce the corresponding 'stilbenyl-oxyacetamides' in good yields.

The reactions of pterostilbenoside (trans-3,5-dimethoxystilben-4′-O-β-D-glucoside) and Ar–O–Tr derivatives of resveratroloside (3,5-dihydroxystilben-4′-O-β-D-glucoside) and pinostilbenoside (3-methoxy-5-hydroxystilben-4′-O-β-D-glucoside) with NaOCl and t-BuOCl in the presence of the stable nitroxyl radical TEMPO were studied in various media. It was found that the principal product of pterostilbenoside
紫檀芪苷(反式-3,5-二甲氧基芪-4'-O-β-D-葡萄糖苷)与白藜芦醇苷的Ar-O-Tr衍生物(3,5-二羟基芪-4'-O-β-D-葡萄糖苷)的反应) 和松芪苷(3-甲氧基-5-羟基芪-4'-O-β-D-葡萄糖苷)与 NaOCl 和 t-BuOCl 在稳定的硝酰基自由基 TEMPO 存在下在各种介质中进行了研究。发现紫檀芪苷转化的主要产物是其2,6-二氯衍生物,其中一部分被氧化形成2,6-二氯紫檀芪葡糖苷酸。白藜芦醇苷和松芪苷的三苯甲基醚与次氯酸盐反应形成产物混合物。
