The following compounds were thought to be new: 1,2-mono-O-isopropylidene-D-glucofuranose-3-S-methyl xanthate, m.p. 102°, [Formula: see text] −27.8°; methyl-4,6-O-benzylidene-α-D-glucopyranoside-2,3-di-S-methyl xanthate, m.p. 100°, [Formula: see text] −18.1°; and 1,2;3,5-di-O-methylene-α-D-glucofuranose-6-S-methyl xanthate, m.p. 99°, [Formula: see text] +27.3° in chloroform. Partial hydrolysis of the isopropylidene and methylene derivatives yielded some glucose-3-S-methyl xanthate and glucose-6-S-methyl xanthate as crude sirups. The 6-xanthate greatly excelled the 3-xanthate in stability toward acid. The chromatographic behavior of both was determined.
