Synthesis , Characterization and study the Antimicrobial Activity For Benzo pyran -2-imine and Tetrazole Ring Derivatives

Abstract

         The  derivatives  of [3-(1H-benzo[d]imidazol-2-yl)-2H-chromen-2-imine]L8 and [2-((1H-tetrazol-5-yl)methyl)-1H-benzo[d]imidazole] L7,L9 have been obtained using -(1H-benzo[d]imidazol-2-yl)acetonitrile as starting material .The latter compound was utilized as a key intermediate for the synthesis of new heterocyclic compounds L8,7,9 with good yields. Newly synthesized compounds have been screened for their antimicrobial activity and characterized by analytical and spectral data.
