Darehkordi, Ali,Saidi, Kazem,Ghazi, Somayeh
experimental part, p. 1382 - 1386 (2011/12/13)
A simple, efficient, and cost-effective method for the synthesis of a series of sugar-thiazolidinone derivatives by a one-pot reaction of the corresponding thiosemicarbazone of d-galactose, d-glucose, and d-mannose compounds in the presence of dimethyl or diethyl acetylenedicarboxylate is described. Two different methods were used and high yields were obtained in both cases: (A) in EtOAC-H2O at an ambient temperature and (B) microwave irradiation under solvent-free conditions.

The heterocyclization reaction on thiosemicarbazones having the D-galacto, D-gluco and D-manno configuration was studied. We applied two different acetylating conditions, and the reaction products obtained were identified, spectroscopically characterized, and conformationally analyzed. Using experimental data, we discuss a possible mechanistic pathway for heterocyclization and evaluate the influence of several factors, including starting material configuration, pH of reaction medium, and reaction time.

THIOSEMICARBAZONES, THIOBENZOYLHYDRAZONES, AND THIOCARBONOHYDRAZONES OF MONOSES
Zelenin, K. N.,Alekseev, E. V.,Kuznetsova, O. B.,Terent'ev, P. B.,Lashin, V. V.,et al.
, p. 232 - 239 (2007/10/02)
The structure of the previously described thiosemicarbazones and also the newly synthesized thiocarbonohydrazones of hexozes and arabinose was studied by 13C and 15N NMR spectroscopy in DMSO solutions.The thiosemicarbazones of the monoses are characterize
