title: Generation of cyclopenta[c]chromenes via a palladium-catalyzed reaction of 2-alkynylphenol with 2-alkynylvinyl bromide.
abstract: A palladium-catalyzed tandem reaction of 2-alkynylphenol with 2-alkynylvinyl bromide gives rise to cyclopenta[c]chromenes in good yields. Three bonds are formed during the process and a double insertion of triple bonds is believed to be the key step.
