Abstract: Coumarin-oxazol-5-one (COX), 3a-d, were synthesized with 7-methoxy-2-oxo-2H-chromene-4-carbaldehyde and benzoylglycine derivatives. The characterizations of the COX derivatives by 1H NMR, FT-IR and elemental analysis were achieved. To obtain the photophysical data of the synthesized COX derivatives… read more here.

Abstract: Abstract New anthracene oxazol-5-one dyes featuring an extended π-conjugated electron system have been successfully prepared by Erlenmeyer synthesis, structurally characterized and their spectroscopic properties were investigated by UV–vis absorption spectroscopy and fluorescence spectroscopy. The oxazol-5-ones… read more here.

Abstract: Abstract Three heterocyclic compounds namely: (Z)-4-benzylidene-2-phenyl-1,3-oxazol-5-one (A), (Z)-4-(4-methoxybenzylidene)-2-phenyl-1,3-oxazol-5-one (B), (Z)-4-(2-thienyl methylene)-2-phenyl-1,3-oxazol-5-one (C) were prepared in one step reaction between hippuric acid and benzaldehyde, p-anisaldehyde and thiophene-2-carboxaldehyde, respectively. The prepared compounds were characterized using FTIR and… read more here.
