REACTION OF Δ3-UNSATURATED PENTOFURANOSES WITH ELECTROPHILIC REAGENTS

The reaction of the 5-O-derivatives of 3-deoxy-1,2-O-isopropylidene-α-D-glyceropent-3-enofuranose with iodine or bromine in methanol in the presence of silver carbonate or in inert solvents in the presence of thallium fluoride leads mainly to a mixture of the cyclic product from addition at the Δ3-double bond and an acyclic 3-halogeno-4-keto derivative.In some cases only one reaction product is formed.With mercuric acetate in methanol the opening of the furanose ring in the initial compound is not observed.
