Article abstract of DOI:10.1016/0040-4039(94)80043-X

The tandem Horner-Emmons-Michael reaction of the hemiaminal derived from N-BOC protected pyroglutamic esters with stabilised phosphonates gives 5-substituted prolinates in high diastereomeric and enantiomeric excess through 1,4-asymmetric induction process.
