Highly Regioselective Ring-Opening of Epoxides: Synthesis and Biological Evaluation as Potent Antimicrobial Agents

Abstract

In present work, a convenient method for the nucleophilic ring-opening of epoxides with secondary amine in presence of ethyl acetate as a polar aprotic solvent using catalytic amount of base is described. Present method is highly regioselective and furnishes the products in short time of period with excellent yield. The regioselectivity of this ring opening was confirmed using FT-IR, 1H NMR, 13C NMR, elemental analysis and mass spectral data. The antimicrobial screening of all these synthesized compounds was done against some bacterial and fungal strains in two polar solvents, DMSO and DMF using agar well diffusion method. These compounds showed good inhibition of bacterial strains and potent against fungal strains than standard drug.
