Abstract

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.
