Publikováno v: New Journal of Chemistry. 44:4324-4331
An easy green synthetic approach for fused isoindoloquinazolinones has been developed under neat reaction (yields up to 91%) conditions. This new one-pot tandem methodology involves condensation of readily available anthranilamide with 3-(2-formylcyc

Neat synthesis of c-fused pyrroles and its application to macrolactamization
Autor: Shubhankar Samanta, Sk Asraf Ali, Amit Saha, Anirban Bera
The current study describes an efficient environmental benign synthetic route of N-aryl substituted c-fused pyrrole derivatives via neat approach. It also provides base-mediated intramolecular macrolactamization using amine ester amidation reaction a

Pyrrolo-benzodiazepine fluorophore for trace amount detection of Cu2+ and application in living cells
Autor: Basudeb Dutta, Shubhankar Samanta, Sk Asraf Ali, Kunal Pal, Kuladip Jana, Chittaranjan Sinha, Arup Kumar Adak
Publikováno v: Journal of the Indian Chemical Society. 98:100085
In general, paramagnetic ions serve as fluorescence quencher. Very few fluorogens are known who could enhance emission on binding with paramagnetic transition metal ions. In this work, a novel (3-methoxy-7-pyridin-2-yl-5, 6, 8, 13-tetrahydro-7H-8, 13

Pd-catalyzed C-H Arylation: A General Route for the Synthesis of Benzo[b ]carbazolenaphthoquinones
Autor: Susanta Kumar Manna, Shubhankar Samanta, Arabinda Mandal, Akash Jana, Suresh Kumar Mondal, Sk Asraf Ali
Publikováno v: Journal of Heterocyclic Chemistry. 54:2529-2535
A short, efficient and general methodology for benzo[b]carbazolenaphthoquinones was developed via Pd-catalyzed C-H arylation process. This methodology was successfully applied to the synthesis of highly biologically active compound 5H–benzo[b]carba
