Synthesis of Nitrogen-Containing Heterocycles from the Reaction of Amidrazones with \alpha-Haloesters

Authors: HANY M. DALLOUL, PETER H. BOYLE

Abstract: The reaction of amidrazones 1 with \alpha-haloesters 2 formed 1,3,5-substituted 4,5-dihydro-1,2,4-triazin-6-ones (4a-z) rather than 1,2,4-triazin-5-one derivatives (5a-z). The microanalysis and spectral data of the synthesized compounds are in full agreement with their molecular structure.

Keywords: Amidrazones, \alpha-haloesters, 4,5-dihydro-1,2,4-triazin-6-one
