M. Maeda et al., SYNTHESIS OF A NOVEL DIOXANE NUCLEOSIDE HAVING 2 BASES, -5(R)-HYDROXYMETHYL-3(R)-(URACIL-1-YL)-1,4-DIOXANE AND ITS 2(S)-ISOMER, FROM URIDINE, Tetrahedron letters, 38(39), 1997, pp. 6841-6844
A novel dioxane nucleoside for chemotherapy, )5(R)-hydroxymethyl-3(R)-
(uracil-1-yl)-1,4-dioxane and its 2(S)-isomer, were conveniently synth
esized from uridine with Several steps including periodate oxidation,
partial reduction to form hemiacetals, and glycosidation of the second
base, 5-fluorouracil, using stannic chloride as the catalyst. (C) 199
