Reaction of benzyl 2,3-anhydro-4-O-trifluoromethylsulfonyl-β-L-ribopyranoside (1) and benzyl 2,3-anhydro-4-O-trifluoromethylsulfonyl-α-D-ribopyranoside (4) with malonic acid derivatives yields, via the carbanions, the cyclopropa-monosaccharides 3 and 6.The ester residues attached to the cyclopropane moiety can be saponified to give the corresponding acids which can be coupled to new carbohydrate amino acid derivatives of type 9 which are of biological interest in different immunological assays. Key Words: Carbohydrates / Cyclopropapyranosides / Sugar triflates
