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
