Abstract

A library of isomeric glutamic acid analogs based on the spiro [3.3] heptane skeleton is designed. Two members of the library,(R)-and (S)-2-amino-spiro [3.3] heptane-2, 6- dicarboxylic acid hydrochlorides, were synthesized. The stereochemistry of the synthesized amino acids was determined using 1H–1H-NOESY of their diastereomeric derivatives. The aminocarboxylate moiety and the carboxylic group in the synthesized glutamic acid ...
