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.
The structure of 1,2-O-methylene-α-D-glucofuranose has been proved by preparing the 3,5,6-trimethanesulphonate and the 3,5,6-tri-p-toluenesulphonate derivatives of this compound from the corresponding derivatives of 1,2-O-iso-propylidene-α-D-glucofuranose. The results also constitute an additional proof for the recently established structure of the 1,2;3,5-di-O-methylene-α-D-gluco-furanose.
The 2-, 3-, and 6-O-carboxymethyl-D-glucoses and the 2,3-di-O-carboxymethyl-D-glucose have been synthesized. A solvent system was found which gave complete paper chromatographic separation of these derivatives as well as of those obtained upon hydrolysis of a carboxymethylcellulose.
