“…[5][6][7][8] In addition modifications other than using different carbonyl compounds such as using other reagents than acetic anhydride such as triphenylphosphine 9 are used for the Erlenmeyer reaction. Preparation of oxazolones [10][11][12] using acetic anhydride and α-(α-haloacyl)amino acids as starting materials was reported by Bergmann and Stern. 13 N-Chloroacetylphenylalanine with acetic anhydride were refluxed according to the Bergmann and Stern procedure to give 4-benzylidene-2-methyl-2oxazolin-5-one (Scheme 2).…”

In this research, 15 novel derivatives of the thiazolactone skeleton were synthesized using the Erlenmeyer–Plöchl reaction procedure. Glycine, alanine and leucine amino acids were used to make dithiocarbamate precursor by reacting amino acids with carbon disulfide and benzyl chloride. Obtained benzyl dithiocarbamate underwent thiazolactone formation in the presence of acetic anhydride and then condensed with arylglyoxals as condensing carbonyl group source. Products were characterized using their spectroscopic IR, 1H NMR, and 13C NMR data. In continuation, computational chemistry methods were used to get some information about the products such as structural characteristics, charge distribution, 1H NMR and UV-visible spectra. Results showed that the calculated chemical shifts are in good agreement with experimentally recorded ones. The B3LYP density functional method in conjunction with the 6-311++G(d,p) basis set was used for all calculations.

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 H NMR, FT-IR and elemental analysis were achieved. To obtain the photophysical data of the synthesized COX derivatives were used spectrophotometric and spectrofluorimetric methods. Evaluation of the absorption and emission properties of the structures was carried out in six different solvents. Maximum absorption and emission wavelengths (λ; nm), molar extinction coefficients (ε; cm M), Stoke's shifts (Δλ nm) and quantum yields (ϕ), of the COX derivatives were declared.
