AbstractA series of tetracarboxamide and macrocyclic tripeptides have been prepared starting from 3,5-bis[N-(1-hydrazinyl-1-oxo-3-phenylpropan-2-yl)]pyridinecarboxamide 4 as starting material, which was synthesized from dinicotinic acid 1. Treatment of 4 with 1,4-diaminobutane, 1,6-diaminohexane, or cycloalkanone derivatives gave the corresponding macrocyclic tetracarboxamides (5a, b) and cycloalkyl hydrazone derivatives (6a–c), respectively. Additionally, the reaction of 4 with acetophenone or acetylpyridine derivatives gave the corresponding Schiff base derivatives 7a–e and 8a–c, respectively. Also, carboxylic acid hydrazide 4 was treated with acid anhydrides in glacial acetic acid to afford the corresponding diimide tetracarboxamide derivatives 9a, b, 10, and 11, respectively. The structures of newly synthesized compounds are established by physical and spectral data evidences. Some of the synthesized compounds were screened as antimicrobial agents.

A series of 1-(3,4-dihydro-3-oxo-2H-1,4-benzoxazine-2-carbonyl)-3-methyl-4-(substituted phenylhydrazono)-2-pyrazolin-5-ones have been synthesized by the reaction of 2H-3,4-dihydro-3-oxo-1,4-benzoxazine-2-carboxylic acid hydrazide with substituted acetoacetic ester derivatives using acetic acid as solvent under microwave irradiation (MWI), as well as by conventional methods. The reaction rate is enhanced tremendously and the yields are improved under MWI as compared to conventional methods.
