Synthesis of D-galactose modified 1,3-dithiole-2-thione derivative
A procedure for the synthesis of a D-galactose modified 1,3-dithiole-2-thione derivative is described. D-galactose is converted to 1,2:3,4-di-O-isopropylidene-D-galactopyranose, which is esterified with trifluoromethanesulfonic anhydride. The triflate ester is then treated 2-hydroxyethoxide followed...

| Summary: | A procedure for the synthesis of a D-galactose modified 1,3-dithiole-2-thione derivative is described. D-galactose is converted to 1,2:3,4-di-O-isopropylidene-D-galactopyranose, which is esterified with trifluoromethanesulfonic anhydride. The triflate ester is then treated 2-hydroxyethoxide followed by the tosylation of the hydroxyethylene derivative. The target compound is obtained by replacement of the tosylate with the zinc complex of 4,5-dimercapto-1,3-dithiole-2-thione dianion salt. |
