N2 - A procedure was developed for the selective synthesis of functionalized 4-methylenepyrrolidines by tuning the electron-withdrawing group (ArSO 2, COOEt, ArSO) attached to the acceptor imine nitrogen atom during addition of allyl sulfone carbanions. Sulfone carbanion additions to 2H-azirines were also examined.
