New chiral nitroenamines 4a,b having (S)-2-t-butyldimethylsiloxymethylpyrrolidine as an auxiliary were found to be very effective for asymmetric nitroolefination of α-alkyl-γ- and δ-lactones.The enantiomeric excess of the product increased remarkably in t

New chiral nitroenamines 4a,b were found to be very effective for asymmetric nitroolefination of α-alkyl-γ- and δ-lactones.The enantiomeric excess of the product ran up to 99percent.A possible chelation model for the transition state of the asymmetric nit
