X=Y-ZH SYSTEMS AS POTENTIAL 1,3-DIPOLES. THE STEREOCHEMISTRY AND REGIOCHEMISTRY OF CYCLOADDITION REACTIONS OF IMINES OF α-AMINO-ACID ESTERS.

Article abstract of DOI:10.1016/S0040-4039(00)93177-0

The stereochemistry and regiochemistry of cycloadditions of α-amino acid ester imines is dependent both on imine structure and on the reactivity of the dipolarophile.Phenylglycine imines undergo competing dipole stereomutation and cycloaddition with some dipolarophiles.
