An 'all-water' strategy for regiocontrolled synthesis of 2-aryl quinoxalines

Autor: Banothu Naga Raju, Babita Tanwar, Asit K. Chakraborti, Priyank Purohit, Damodara N. Kommi, Dinesh Kumar

Publikováno v: RSC Advances. 5:11873-11883

A new synthetic strategy of tandem N-aroylmethylation-nitro reduction–cyclocondensation has been developed for the first and generalized regioselective synthesis of 2-aryl quinoxalines adopting “all water chemistry.” Water plays the critical ro

Silver nanoparticle-catalysed phenolysis of epoxides under neutral conditions: Scope and limitations of metal nanoparticles and applications towards drug synthesis

Autor: Bhavin V. Pipaliya, Sudipta Raha Roy, Damodara N. Kommi, Kapileswar Seth, Asit K. Chakraborti

Publikováno v: Journal of Molecular Catalysis A: Chemical. 392:164-172

Chemo- and regio-selective epoxide phenolysis is reported for the first time under neutral condition catalysed by silver nanoparticles. Other metal nanoparticles (e.g., Au, Pd, Cu, In, and Ru) are less effective. The choice of solvent is critical wit
