via the palladium-catalyzed [4+2] homobenzannulation of conjugatedenynes 4 was developed. In all cases, the reactions proceeded in regiospecific manner, affording the disubstituted styrenes, bearing various functional groups at the 2 and 6 positions of the benzene ring, as a single reaction product in good to excellent yields. Initial attempts at cross-cycloaddition of two different enynes indicated
