The effects of bromine atoms on the photophysical and photochemical properties of 3-cinnamoylcoumarin derivatives

Eight coumarin derivatives (T1-T8) with or without modification using one or two bromine atoms were synthesized through the aldol condensation reaction. Their photophysical, photochemical and electrochemical properties were investigated. It was shown that

Synthesis of some interesting new heterocyclic compounds containing coumarin moiety

SYNTHESIS of 3-acetyl-6-substiluted coumarin 1a-c have been carried out. The reaction of 3-acetyl-6-broniocoumarin 1b with ethyl oxalate in the presence of sodium metal afforded the corresponding 3-coumarinyl pyruvic acid derivative 2, which converted int

A facile one pot synthesis of 2-aryl-4-[2H-2-oxo-[1]benzopyran-3-yl] 2,3-dihydro and 2,5-dihydro-1,5-benzothiazepines

3-acetyl coumarins on condensation with various aromatic aldehydes in the presence of piperidine gave corresponding chalcones in a solid state under solvent free conditions. These chalcones are isolated and characterized. The insitu-formed chalcones (1) a
