✦ Synopsis
The syntheses of the heretofore unknown 2-B-D-ara and P-B-D-xylofuranosyl isomers of the antitumor agent tiazofurin have been accomplished. In both cases the stereospecific inversion of the required 2' or 3'-hydroxyl group in the protected parent compound afforded the desired products.
In 1982 it was reported that 2-B-D-ribofuranosylthiazole-4-carboxamide
