Abstract

Asymmetric Michael reaction of phosphinic or aminophosphinic acids with acrylate derivatives afforded phosphinyl dipeptidomimetics in excellent yields (>90%). Chiral induction of substituents at the α-position of acrylate derivatives of Evans oxazolidinone type auxiliaries was obtained in moderate to excellent diastereomeric and enantiomeric excesses (50–98%). Pure diastereomers and enantiomers of phosphinyl dipeptidomimetics 16– 19 were also successfully separated by HPLC.
