The present invention relates to a new process in 3 steps starting from 2-C-methyl-D-ribopentono-1,4-lactone for the preparation of tetra-acyl ribofuranose derivatives of Formula (I) useful in the synthesis of nucleotides.
Efficient syntheses of 2-C-trifluoromethyl D- and L-ribose and some O-glycosides via trifluoromethylation of D- and L-3,4-O-isopropylidene-β-erythro-pentopyranosid-2-ulose with Ruppert's reagent are described.
