Abstract
The peracetylated β-allyl C-glycosides of d -ribofuranose (8 )
and 2-deoxy-d -ribofuranose (13 )
were stereoselectively prepared via the isopropylidene derivatives 3 and 4 . These
reactions represent what are, to the best of our knowledge, the
first preparation of these apparently simple derivatives whose structures
were carefully proved by NMR and X-ray investigations. Publications which
allegedly described the synthesis of 8 and 13 were critically examined.
Key words
allylation - glycosylation - C-glycosides - nucleosides - stereoselectivity
