title: Methylenecyclopropanes in [4+1] cycloaddition with enones.
abstract: A nickel-catalyzed [4+1] cycloaddition of enones with methylenecyclopropanes leading to dihydrofurans was developed. The reaction outcome is attributed to the transformation of methlenecyclopropane, which is incorporated into a five-membered ring as a one-carbon fragment.
