An efficient method for the desulfurization–oxygenation of 1,3-thiazolidine-2-thiones and 1,3-oxazolidine-2-thiones using propylene oxide and employing microwave irradiation is described. This strategy of oxygenation of the thiocarbonyl group provides an attractive methodology to prepare chiral 1,3-thiazolidin-2-ones and 1,3-oxazolidin-2-ones from the corresponding precursors in good yields.
1,2,3-triazoles were synthesized using several alkynes and azides as starting materials in the presence of glucose and catalytic amounts of Fehling reagent. This process is carried out under ambient pressure and temperature with good yields Keywords: Alkynes, azides, Fehling reagent, glucose, 1,2,3-triazoles, copper, pressure, temperature, triazole, sodium
A new method for the conversion of trichloromethyl compounds into the corresponding phenylthiomethyl derivatives by reaction with sodium thiophenolate in the presence of thiophenol is described. This transformation proceeds at room temperature in high yield and has been applied to a variety of trichloromethyl compounds.
