Treatment of 2, 2'-anhydro-1-(3, 5-di-O-acetyl-β-D-arabinofuranosyl) uracil (II) with sodium ethanethiol afforded 1-(3-ethylthio-3-deoxy-β-D-xylofuranosyl) uracil (IV) in 90% yield. Hydrogenation of 2, 2'-anhydro-1-(5-O-benzoyl-3-O-mesyl-β-D-arabinofuranosyl)-uracil (III) with Raney nickel resulted in formation of the 5, 6-dihydro derivative (VI). 5'-O-Benzoyl-2'-bromo-2'-deoxy-3'-O-mesyluridine (VII) was hydrogenated in the presence of Pd·BaSO4 or Raney nickel to yield 5'-O-benzoyl-2', 3'-dideoxyruidine (VIII). VIII was treated with alkali to give 2', 3'-dideoxyuridine (IX) in 50% overall yield from uridine. The mechanism of the reductive elimination of the cis-bromohydrin mesylate (VII) was presented. The treatment of VII with sodium methoxide in methanol gave 1-(2-bromo-2, 3-dideoxy-2-ene-β-D-glyceropentofuranosyl) uracil (XII) which was converted to IX by the catalytic hydrogenation. Bromination of IX afforded 5-bromo-2', 3'-dideoxyuridine (XIV).
