  • ?-1-phosphorylated-2-deoxy-2-fluoroarabinoside and process for producing 2?-deoxy-2?-fluoro-?-d-arabinonucleoside
    Patent number: 7381820
    Abstract: A method for producing 2?-deoxy-2?-fluoro-?-D-arabinonucleoside represented by formula (II): (wherein B represents a base), in particular, 2?-deoxy-2?-fluoro-?-D-arabinopurinenucleoside, which method comprises causing a nucleoside phosphorylase to act on ?-1-phosphorylated-2-deoxy-2-fluoroarabinoside represented by formula (I): or a mixture of ?- and ?-isomers of 1-phosphorylated-2-deoxy-2-fluoroarabinoside represented by formula (V?): and on a base. The compound can be produced at high yield and in a convenient and highly stereoselective manner.
