A palladium-catalyzed [3 + 2] cycloaddition of cyclopropenones with N-allenamides has been developed. This methodology facilitates the synthesis γ-amino-α'-methylenecyclopentenones in moderate to excellent yields good regioselectivity and compatibility various functional groups. The employment as versatile 2C synthons enables simultaneous incorporation both a nitrogen atom methylene group into cyclopentenones. Furthermore, this approach exhibits reverse when compared general allenes. Density theory calculations successfully elucidated origin observed regioselectivity.
