“…[2][3][4] Different sources of carbonyl functional group containing compounds are used to synthesize various Erlenmeyer products. [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.…”

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.

“…The use of these dyes results from the combination of the properties of the azo group and several types of aromatic-substituted substrates that confer thermal and photochemical stability and an intense colour over the visible range [1]. Azo dyes are used in optical recording media [2], toners [3], ink-jet printing and oil-soluble light fast dyes [4]. They have been reported to show antineoplastic, antidiabetic, antiseptics, antibacterial, antitumour [5] and antitrypanosomal [6] activities.…”

4‐Phenyl‐2‐aminothaizole was diazotized and coupled with N‐(alkyl)‐2‐oxo‐3‐cyano‐4‐methyl‐6‐hydroxypyridine (2‐pyridone). The resultant dyes were named as N‐(alkyl)‐6‐hydroxy‐4‐methyl‐2‐oxo‐5‐((4‐phenylthiazole‐2‐yl)diazenyl)‐1,2‐dihydro pyridine‐3‐carbonitrite and duly characterized. The diazotized aryl amines were then coupled to a moiety of above‐mentioned dyes at 5‐position of thiazole. The obtained bisheteroaryl azo dyes were characterized by elemental analysis and spectral studies. Solvent effects on the visible absorption spectra of the dyes were evaluated. The color of the dyes is discussed with respect to the nature of the heterocyclic ring, aromatic amines, and substituents present therein. All these dyes were applied as disperse dyes on to polyester fabrics, and their fastness properties were evaluated. © 2013 Wiley Periodicals, Inc.
