enzymatic, and chemical synthesis approach that applies an enzymatic conversion from adenosine to inosine followed by a ring-cleavage of the protected inosine. A direct phosphorylation of the resulting 2',3'-isopropylidine acadesine (5) was developed to yield the title compound in 99% purity following ion exchange chromatography.

Synthesis of [13C5]-labeled anti-HIV nucleosides, e.g. d4T, ddI, ddA, is described. The methodology used has been optimized due to the very high cost of the starting compound. The key step of this approach was the stereoselective dehomologation of 1,2:5,6-di-O-isopropylidene-3-oxo-α-d-glucofuranose (2) with periodic acid and sodium borohydride, which gave optically pure ribose derivative as the exclusive
