Abstract

PURPOSE: a-Amino acid derivatives of formula I (R is a-amino acid radical; R' is H, protective group, salt-forming cation; R3 is H, alkyl; X is O, S; A is substd. or unsubtd. alkyl, alkenyl, alkadienyl, cycloalkyl, aryl); for example, D(-)-a-(4-Me-2, 3-dioxo-1-piperazinocarbonylamino) phenylacetic acid.
