Irreversible, acid-catalyzed 2 --> 1 transglycosylation reactions of fully acetylated beta-D-ribofuranosylindazoles were studied applying HPLC analysis. Results so obtained support the intermolecular mechanism of transglycosylation via a 1,2-diglycosylindazole intermediate and are compared to those of the purine series.

the nature and stereochemistry of the d -aldopentofuranose and the effect of the substituent at C-2 have been investigated by using indazole as a model heterocycle. The results obtained show that the nature and stereochemistry of the starting, per-O-acetylated d -aldopentofuranose have no significant effectupon the productdistribution of the acid-catalyzed fusion-reaction.
