A series of 2-amino benzoic acid derivatives (1-28) were synthesized and evaluated for their in vitro antimicrobial activity against the panel of Gram positive, Gram negative bacterial and fungal strains. The results of antimicrobial studies indicated that, in general, the synthesized compounds were found to be bacteriostatic and fungistatic in action. QSAR studies performed by the development of one target and multi target models indicated that multi-target model was effective in describing the antimicrobial activity as well demonstrated the effect of structural parameters viz. LUMO, (3)chi(v) and W on antimicrobial activity of 2-amino benzoic acid derivatives.

Intramolecular Metal-Free Oxidative Aryl-Aryl Coupling: An Unusual Hypervalent-Iodine-Mediated Rearrangement of 2-Substituted<i>N</i>-Phenylbenzamides
Hypervalent‐iodine‐mediated oxidative coupling of the two aryl groups in either 2‐acylamino‐N‐phenyl‐benzamides or 2‐hydroxy‐N‐phenylbenzamides, with concomitant insertion of the ortho‐substituted N or O atom into the tether, has been described for the first time. This unusual metal‐free rearrangement reaction involves an oxidative C(sp2)C(sp2) aryl–aryl bond formation, cleavage of a C(sp2)C(O) bond
