Reaction of 2-Aminobenzoylhydrazines with Carboxylic Acids: Formation of Quinazolin-4(3H)-one, 1,3,4-Oxadiazole and 1,3,4-Benzotriazepin-5-one Derivatives

Reactions of 2-aminobenzoylhydrazines with aliphatic acids give 1-(2'-acylaminobenzoyl)-2-acylhydrazines (4) which are cyclised to 3-amino-2-alkylquinazolin-4(3H)-ones (6).Aromatic acids react with 2-aminobenzoylhydrazines to give a mixture of 1-(2'-amino

Reaction of N-Alkyl/Aralkylisatoic Anhydrides with Aroylhydrazines: Formation of 1,3,4-Oxadiazoles and 1,4-Dihydro-5H-1,3,4-benzotriazepin-5-one

The reaction of N-alkyl/aralkylisatoic anhydrides with aroylhydrazines in refluxing acetic acid/p-toluenensulfonic acid furnish 2-(2-alkylaminophenyl)-5-aryl-1,3,4-oxadiazoles (4) and 1-(2-alkylaminobenzoyl)-2-benzoylhydrazines (3).Cyclisation of 3 using DCC affords 1,4-dihydro-5H-1,3,4-benzotriazepin-5-ones (5).

Reaction of 2-Aminobenzohydrazides with Schiff Bases. A New Route to 3-Benzylideneamino-4(3H)-quinazolinones and 2--5-aryl-1,3,4-oxadiazoles

Reaction of 2-aminobenzohydrazides with Schiff bases in methanol followed by KMnO4 oxidation has resulted in the presence formation of 3-benzylideneamino-4(3H)-quinazolinones and 2--5-aryl-1,3,4-oxadiazoles, characterized by spectra
