Chromatographic and chromato-mass spectral characterization of amino acids derivatives formed via the interaction with dimethyl acetal of dimethylformamide

A series of amino acids have been converted into the derivatives via interaction with dimethylformamide dimethyl acetal for gas chromatography identification. The derivatives have been for the first time characterized with mass spectra and retention indices corresponding to the standard nonpolar polydimethylsiloxane stationary phases. Basic features of mass spectroscopic fragmentation of the derivatives have been stated; the rules for interpretation of their gas chromatography retention indices have been figured out, including the additive scheme elements.

Transformation of the amino group of amino acids into an amidine and subsequent treatment with hydrazine leads to 1,2,4-triazine-6(1H)-ones.The method described is a new synthetic approach.Unsaturated amino acids gave imidazol-5-one derivatives after the
