[摘要]: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 (Ag2O, Ag2CO3, MnO2, and FeCl3 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. |
