“…1-Deoxy-l-fructose, (3), may be prepared by the microbiological oxidation of l-rhamnitol, (1) (Izumori, 2006b), or by chemical synthesis from l-arabinose, (2) (Jones, Jenkinson, Soengas, Fanefjord et al, 2007). In aqueous solution, the deoxyketose (3) exists as an equilibrium mixture of the open chain (3)-keto, -pyranose (3)-pyr, -furanose (3)-fur,pyranose (3)-pyr and -furanose (3)-fur forms.…”
