Intramolecular heterocyclization of N-allyl(phenyl)thiosemicarbazides of morpholinylacetic acid
摘要:
Intramolecular heterocyclization of N-allyl(phenyl)thiosemicarbazide of N-morpholinylacetic acid in aqueous alkaline medium results in cyclic 5-(morpholinomethyl)-4-allyl(phenyl)-1,2,4-triazole-3-thiones.
Chemical transformations of N-morpholinylacetic acid hydrazide and steric structure of its derivatives
摘要:
The reaction of N-morpholinylacetic acid hydrazide with various isothiocyanates and potassium thiocyanate resulted in the corresponding potentially biologically active thiosemicarbazide derivatives. Potassium N'-(2-morpholin-4-ylacetyl)hydrazinocarbothioate was synthesized and involved into heterocyclization in acidic environment to yield cyclic 5-(morpholinomethyl)-1,3,4-thiadiazole-2-thione. The structure of the synthesized compounds was established by IR, H-1 NMR spectroscopy, mass spectrometry, and XRD analysis.
