Abstract :

The preparation of C-13-labeled ribonucleosides starting from D-[C-13(6)]glucose in 45% overall yield is described. The key of this short synthetic way is the dehomologation of di-O-isopropylidene hexofuranose 2 with periodic acid and NaBH4 that afforded stereoselectively the labeled ribofuranose derivative 3 in high yield.
