The cleavage of the oxirane ring of 3,4-anhydro-2deoxy-D-threo-pentose diethyl acetal by (isopropoxy)-titanium fluorides is discussed. The high regioselectivity found with bis(isopropoxy) titanium difluoride is the basis for an enantioselective synthesis of 3-fluoro-2,3-deoxy-D-erythreo-pentose from a non-carbohydrate precursor.
