Gold(I)-Catalyzed Synthesis of Dihydrobenzofurans from Aryl Allyl Ethers

Abstract

Formation of dihydrobenzofurans from aryl allyl ethers was catalyzed by in situ generated PPh₃AuOTf. This reaction ­appears to proceed by a Claisen rearrangement, followed by addition of the resulting phenol to the allyl group.

Key words

homogeneous catalysis - gold - cyclization - alkenes - Claisen rearrangement
