Abstract

Abstract Some substituted 4-formylcoumarins were prepared by oxidation of 4- corresponding formylcoumarins using SeO2. These aldehydes were converted to thiosemicarbazones by condensation reaction with tetra-O-acetyl-bD-glucopyranosyl thiosemicarbazide usingmicrowave-assisted heating method. The synthesized compounds were characterized by FT-IR and 1H NMR, 13C NMR and mass spectral studies.
