摘要：
A series of 2-aryl- and 2-heteroaryl-substituted 3,5-dimethoxy-1,4-benzoquinones (compounds 27-36) have been synthesized by cross-coupling of (2,3,4,6-tetramethoxyphenyl)boronic acid (2) with aromatic bromides or iodides in the presence of [Pd-0(Ph-3)(4)] and Na2CO3, followed by AgO-promoted oxidation of the resulting biaryl compounds 17-26.
