Characterization and Biological Screening of Newly Synthesized Derivatives of Coumarin

It is well known that coumarins show variety of biological properties. In addition to this five membered heterocycles like triazole, thiazolidinone and oxazolidinone are also biologically active. Referring our previous work, which exhibited antimicrobial activity to 1, 3, 4-oxadiazole group of 3-carbethoxy-2-oxo-2H-benzopyran, in this scheme we carried out the synthesis of new derivatives like triazol, imine, thiazolidinone and oxazolidinone on coumarin. All the synthesized compounds established on the basis of spectral techniques and evaluated for their antimicrobial study.
