The first preparation of α-functionalized benzylamine

Abstract We have investigated the α-acetoxylation of benzylamine derivatives 4 from substituted benzylphthalimide 3 using NBS/AcONa/AcOH in chlorobenzene at reflux.

Antimicrobial and docking studies of (−)-catechin derivatives

Antimicrobial activities of (−)-catechin derivatives were assayed for their antibacterial and antifungal activities against gram positive, gram negative bacteria, and fungi. Most of the compounds significantly active among which Compounds 1a, 1b, and 1c showed excellent antibacterial for both gram negative and gram positive bacteria, these compounds also exhibited excellent antifungal activity more than the standard drug. Molecular docking studies of Compounds 1a and 1b established good binding affinity with ATP-binding pocket of DNA gyrase and are in favor of the observed biological activity. These data collectively suggest that Compounds 1a and 1b could serve as a novel antimicrobial agent.
