摘要
A new and convenient synthetic method has been developed for the construction of stilbenes bearing electron-withdrawing group(s) by using benzils and arylmethyldiphenylphosphine oxides via sequences involving Wittig-Horner reaction and a rearrangement in the presence of t-BuOK in toluene under mild conditions. This approach could be readily applied to a facile synthesis of biologically important natural products, resveratrol and its derivatives, such as trimetboxystilbenes 1 (Z) and 2 (E).
