Gas chromatographic mass spectrometric identification ofN-dicarboxylmonoglycines

Abstract
A number of N‐dicarboxylmonoglycines of biological interest have been synthesized. They were characterized by means of mass spectrometry. Gas chromatography of the methyl esters of methylmalonyl‐, succinyl‐, glutaryl‐, adipyl‐, suberyl‐ and sebacylglycines showed a single sharp peak for each compound on Dexsil 300 and OV 17 columns. Methylene unit values and mass spectra of the six methyl esters are reported.
