Access to 6H-naphtho[2,3-c]chromenes by a palladium-catalyzed reaction of 2-haloaryl allene with 2-alkynylphenol.
A palladium-catalyzed reaction of 2-haloaryl allene with 2-alkynylphenol is described, leading to 6H-naphtho[2,3-c]chromenes in good to excellent yields. This transformation proceeds efficiently with excellent chemoselectivity and regioselectivity.
