[摘要]:The peracetylated beta-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. |
