  An improved asymmetric nitroolefination of α-alkyl-γ- and δ-lactones with modified nitroenamines

  摘要：

  New chiral nitroenamines 4a, b were found to be very effective for asymmetric nitroolefination of alpha-alkyl-gamma- and delta-lactones. The enantiomeric excess of the product ran up to 99%. A possible chelation model for the transition state of the asymmetric nitroolefination was discussed.

  New chiral nitroenamines 4a,b having (S)-2-t-butyldimethylsiloxymethylpyrrolidine as an auxiliary were found to be very effective for asymmetric nitroolefination of alpha-alkyl-gamma- and delta-lactones. The enantiomeric excess of the product increased remarkably in the reaction with gamma-lactones compared with previous nitroenamines 1a,b. A possible chelation model for the transition state of the asymmetric nitroolefination is discussed.
