Abstract
Abstract A novel protocol to synthetic transformation of 4H-chromenes into dihydrofurans (3) and 2H-chromenes (11) promoted by hypervalent iodine has been accomplished in a one-pot reaction at ambient temperature. Dihydrofurans are exclusively formed under basic reaction conditions, whereas, 2H-chromenes are the products under acidic condition. Simple reaction conditions with a broad substrate scope inclusive of various heterocycles and high yields are the attractive features of this protocol. Graphical Abstract
