Abstract

Glycosides of 2-deoxy and 2,6-dideoxy carbohydrates were built up in high yields and with high stereoselectivity in 0.1 M LiClO4/Et2O mixtures; the glycosidations proceed under neutral conditions and without need for an additional promoter such as a strong Lewis acid, a heavy metal salt or an alkylating reagent.

Schmidt, J. Michel and M. Roos, Liebigs Ann. Chem., 1984, 1343 Search PubMed; The corresponding β-anomer was obtained by employing K2CO3 as base. In both cases the yield was quantitative. Glycosyl fluorides 2–4 were obtained in quantitative yield by treatment of the corresponding 1-O-deprotected benzylated carbohydrates with diethylamino sulfur trifluoride (DAST) in CH2Cl2 according to the general procedure (W.
