摘要：

Series of di-and trisubstituted conjugated enynes 3 in the presence of Pd(PPh3)(4) catalyst underwent [4+2] cross-benzannulation reaction with conjugated diynes 4 affording polysubstituted benzenes 5 in reasonable to excellent chemical yields. In all cases the cycloaddition reaction proceeded in regio-and chemospecific manner. (C) 1997 Elsevier Science Ltd.
