3-Arylhydrazono-2,4-dioxo-4-phenylbutanoates have been prepared by the coupling of benzoylpyruvate with aryldiazonium chlorides. Reactions of the 3-arylhydrazono-2,4- dioxo-4-phenylbutanoates with 1-aminoguanidine, semicarbazide, and thiosemicarbazide gave 5-substituted 2-imino-6-azauracil (3a), 6-azauracil (3b), and 2-thio-6-azauracil (3c), respectively. The analytical data of these compounds ...

The aim of the present study was to synthesize and characterize divalent metal ions Nickel, Copper Zinc complexes 5-chloro 2-furaldehyde thiosemicarbazone. Firstly ligand prepared from reaction between 5-Chloro-2-furaldehyde thiosemicarbazide, second step involved synthesis Ni(II), Cu(II) Zn(II) compounds (ligand or complex) characterized using different analytical techniques such as elemental ...

Macrocyclic Schiff bases have been synthesized by the condensation of acetyl acetone with semicarbazide hydrochloride and thiosemicarbazide in presence of methanol. Further, their oxovanadium complexes have been synthesized by using vanadium acetylacetone. The structural assignment of these compounds has been made on the basis of MP, TLC, MW determination, conductivities, elemental analysis and...

A series of zingerone?thiohydantoin hybrids were synthesized from O-alkyl zingerone derivatives by cyclocondensation with thiosemicarbazide in a two-step reaction. The obtained new potentially bioactive compounds structurally characterized IR and NMR spectroscopy, as well elemental HRMS analysis. In addition, their antimicrobial vitro anticancer activities tested. tested showed low to moderate ...
