Implication of carbonic anhydrases (CAs) in many physiological functions made them attractive therapeutic targets. Herein, we report the synthesis of three series of benzenesulfonamide-based compounds (5a-e, 9a-e and 10a-e) as potential ligands to four of

New multipurpose arylation/acylation/transamination reagents, N-acylisatins, have been developed by selective ‘inside-outside’ C?N bond cleavage under different catalytic conditions. As activated amides, N-acylisatins undergo Rh-catalyzed C?H arylation and Pd-catalyzed acylation by cleavage outside the C?N bond, and the desired biaryls and diaryl ketones were obtained in good to excellent yields. Generally, the combination of N-acylisatins with amines leads to a ring-opening reaction and formation of transamination products in a predictable manner through inside C?N bond cleavage. Interestingly, treatment of N-acylisatins with amines lead to unexpected outer-ring transamination products when CsF is added, which shows that CsF can favor the outside C?N bond cleavage path. Notably, this work presents a new strategy for multiple chemical transformations of a single amide to achieve various products by selective C?N bond cleavage. (Figure presented.).

The first example of an intramolecular decarboxylative acylation reaction for the synthesis of 4H-benzoxazin-4-one derivatives has been described. The silver-mediated reaction has a broad substrate scope and provides a mild and rapid approach to the corre

A series of N-aroylated isatins 1-15 was synthesized and evaluated for their antiglycation activity. All compounds showed a varying degree of glycation inhibitory activity with IC50 values between 18.01 ± 0.05-693.7 ± 3.0 μM, when compared with the standard (aminoguanidine) having an IC50 = 268.7 ± 12.4 μM. Compound 1 was found to be the most active member of this series with an IC50 = 18.01 ± 0.05 μM. Compound 10 showed an IC50 = 72.5 ± 0.09 μM, whereas compound 7 has an IC50 = 80.18 ± 0.07 μM. Compounds 3, 9, and 13 showed IC50 values 170.2 ± 0.62, 117.91 ± 2.9, 171.3 ± 0.79 μM, respectively. Rest of the compounds along with parent isatin were found to be inactive. The structures of all the synthetic compounds were deduced by spectroscopic analysis.
