Abstract Semicarbazones have a great interest because of their chemistry and biological activities for the treatment of various human ailments. A series of seven vanillin semicarbazones (3a-g) were synthesized by reflux of aryl semicarbazides with appropriate carbonyl compound in the presence of glacial acetic acid. The aryl semicarbazides (2a-g) were synthesized from aryl carbamates by reacting with hydrazine hydrate and ethanol on ...
