1,2,4-Triazin-6(1H)-ones 3 have been prepared by cyclization of α-ketoacyl chlorides 15 with amidrazones 14. 4,5-Dihydro-1,2,4-triazin-6(1H)-ones 5 were obtained by cyclization of amino acid hydrazides 10 with orthocarboxylates 11.Key Word: 1,2,4-Triazin-

The 2-aminoacylhydrazines form 1,4,5,6-tetrahydro-1,2,4-triazin-6-ones with orthoesters and iminoesters.Benzylidene and isopropylidene derivatives of the 2-aminoacylhydrazines give the corresponding derivatives of 3-amino-1-imidazolin-4-ones with the same

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
