Reaction mechanisms consistent with the formation of isopropylidene-like trans-furanose-3′,5′-[2-(R)(S)-aminochlorofluoromethyl-1,3-dioxanyl]-2′-deoxynucleoside intermediates 6, O2,3′-anhydro-2′-deoxynucleosides 7 and other minor reaction products and the yield-limiting effect of 6 on the cyclization of 7 are proposed.
