PREPARATION, SPECTRAL AND PHYSICOCHEMICAL CHARACTERISTICS OF METHYLAMIDE Nα-PHENYLTHIOCARBAMOYL DERIVATIVES OF NATURALLY OCCURING AMINO ACIDS
The methylamide Nα-phenylthiocarbamoyl derivatives of encoded amino acids II were prepared either by the addition of phenylisothiocyanate to amino acid methylamides or by the treatment of amino acid phenylthiohydantoins (5-alkyl-3-phenyl-2-thioxo-4-imidazolinones) I with methylamine.The derivatives were prepared of 19 amino acids and their melting points, 1H NMR, 13C NMR, mass, ultraviolet and infrared spectra were measured.
