generated in situ from α-alkynylenones and gold catalysts were successfully used for borane-catalyzed amine C−H functionalization reactions, giving amine derivatives bearing a furan ring. The reactions took place either via an α-furylation pathway or via a [3+2] cycloaddition pathway, depending on the alkyl groups attached to the amine.
