ChemInform Abstract: A Novel Method to Access Chiral Nonnatural 2,4‐Disubstituted Pyrrolidines from Aldehydes and Nitroolefins Only with an α‐Substituent.

Abstract γ‐Nitro carbonyl products (III) are obtained in good yields and stereoselectivities via the organocatalytic asymmetric Michael addition of nitroolefins (II) with aldehydes (I).
