addition of chiral phosphine, that is, (R)‐ or (S)‐SITCP, to an α‐substituted allene ester generated a zwitterionic dipole. Under optimized reaction conditions, this dipole could engage isatine‐derived N‐Boc‐ketimines in a novel mode of [3+2] annulationreaction. Pyrrolinyl spirooxindoles are thus afforded in high yields and with excellent enantioselectivities. The unprecedented annulationreaction successfully
2-imino-5-oxopyrrolidine-3-carboxylates in good yields. A new efficient synthesis of pyrrolidin-2-ones via sequential Wittig reaction/nucleophilic addition/cyclization was developed. The Wittig reaction of the phosphoranes with isocyanates produced ketenimine intermediates that were then treated with primary amines to give amidines, which were treated with catalytic sodium alkoxide to give 2-imino-5-o
