Bioactive Heterocycles

The use of microwave energy for the synthesis is considered as one of the alternate strategies. The present work includes the synthesis of some newer 2,5-disubstituted-1,3,4-oxadiazole analogues using both conventional and alternate rapid methods.The conventional method involves the synthesis of the target molecules by using cyclodehydrating agent like POCl3, while the other method consists of using some catalytic reagents like PbO2. Also, the short reaction time provided by microwave synthesis makes it ideal for the reaction. Hence, this project describes an efficient and operationally simple method for the microwave-assisted synthesis of some bioactive heterocycles based on NSAIDs.

The Stability

In this article, we build upon our recent efforts that have focused on demonstrating the value of microwave-assisted synthesis in polyoxometalate (POM) chemistry. Herein, we report for the first time a microwave-assisted approach that enabled the facile preparation and crystallization of a large POM-containing coordination complex. The judicious selection and reaction of a sparingly water-soluble transition-metal-substituted polyanion (TMSP) salt with the tritopic ligand 2,4,6-tris(4-pyridyl)-1,3,5-triazine (TPT) in a mixed solvent system under moderately forcing conditions yields Ba9[(BIIIWVI 11O39CoIII)3(C18H12N6)]·38H2O in moderate yield. Crystallographic analysis reveals significant intermolecular interactions between the organic ligand and neighbouring polyanions, predominantly C—H...O(water) in nature; meanwhile, the solvated regions of the crystal show significant disorder. To supplement the crystallographic study, combustion analysis, and IR and 1H NMR spectroscopic analyses were conducted, revealing good bulk purity and the stability of the complex in aqueous media.

N-Phenylanthranilic acid derivatives were synthesised using the Ullmann condensation of 2-chlorobenzoic acid with aniline derivatives under microwave irradiation in aqueous media. The method offers better yields in shorter reaction times compared to classical heating approaches using water as solvent.
