title: Synthesis of 2-vinylbenzofurans via the copper-catalyzed multicomponent reactions involving an oxa-Michael/arylation/vinylation cascade.
abstract: 2-Vinylbenzofurans have been synthesized via the copper-catalyzed one-pot, three-component reactions of o-iodophenols, in situ generated allenes, and dichloromethane. Cascade transformation of oxa-Michael addition, C-arylation, and sp(3)C-H/sp(3)C-Cl conversion-based vinylation has been involved in realizing the construction of this 2-vinylbenzofuran framework.
