Nitroalkenes readily undergo palladium-catalyzed [3 + 2] cycloaddition with trimethylenemethane to generate nitrocyclopentanes in excellent yield and enantioselectivity. Nitrocyclopentanes are highly versatile synthetic intermediates and provide convenient access to both cyclopentylamines and cyclopentenones.
