在不同溶剂体系(苯-丙酮和二氯甲烷)中,用Ag(2)O、Ag(2)CO(3)、MnO(2)和FeCl(3)中心点6 H(2)O等金属氧化剂,通过3,5-二叔丁基白藜芦醇的区域选择性氧化偶联反应,合成了一系列天然白藜芦醇二聚体。这些偶联产物的后续脱丁基化产生外消旋的pallidol和ampelosin F。
A wide array of natural resveratrol dimers was prepared by the regioselective oxidative coupling reaction of 3,5-di-(tert-butyl) resveratrol using several types of metal oxidants (Ag(2)O, Ag(2)CO(3), MnO(2), and FeCl(3)center dot 6H(2)O) in different solvent systems (benzene-acetone and dichloromethane). Subsequent debutylation of these coupling products resulted in racemic pallidol and ampelosin F.
