Synthesis and desulfurization-decarboxylation of cyclic thionocarbonates of glycerol 1-ethers
Journal of Lipid Research, 1969 A method is described for the synthesis of cyclic thionocarbonates of 1-O-alkyl glycerols in quantitative yield. These derivatives of glycerol ethers can be quantitated by UV absorbance, analyzed by gas-liquid chromatography, or quantitatively converted ...
