Abstract
Eleven biologically interesting N-acylglycines have been synthesized and the gas chromatographic and mass spectrometric properties of their trimethylsilyl derivatives studied, A sharp and reproducible gas chromatographic peak could be obtained for each N-acylglycine as the N, O-bis-(trimethylsilyl)-N-acylglycine. By the use of these derivatives a sensitive and specific selected ion monitoring method for the determination of N-acylglycines in human urine has been developed.
