Reactions of Chiral Azomethine Ylides

Reactions of chiral azomethine ylides usually derived from imines of a-amino acids have been achieved with electron-deficient alkenes and a, 3-unsaturated carboxylic acid derivatives furnishing pyrrolidines. 

Cyclic Five-membered Chiral Azomethine Ylide Precursors 

Chiral Aziridines as Precursors for Azomethine Ylides Type of Aziridine 

Aziridines of type A, with a chiral substituent located at the nitrogen atom have been applied successfully in asymmetric syntheses with a,p-unsaturated carboxylic acid derivatives derived from Oppolzer s chiral camphor sultam.

Other 1,3-dipolar cycloadditions of chiral azomethine ylides with Cgo (98) and reactions of chiral azomethine ylides derived from l-benzyl-4-phenyl-2-imidazoline with different electron-deficient alkenes have been performed (99).
