Methyl 2,3-<I>O</I>-isopropylidene-β-D-ribopyranoside gave efficiently (in 4 steps) methyl 4-deoxy-4-[dimethoxyphosphinyl and (methoxy)phenylphosphinyl]-2,3-<I>O</I>-isopropylidene-β-D-ribopyranosides (ca. 30% overall yield). These were led (in 2–3 steps) to the title compounds and then converted into 1,2,3,5-tetra-<I>O</I>-acetyl-4-deoxy-4-(methoxyphosphinyl and phenylphosphinyl)-D-ribofuranoses, whose structures and <SUP>3</SUP><I>T</I><SUB>2</SUB> (and <SUP>2</SUP><I>T</I><SUB>3</SUB>) conformations were established by spectroscopy.
