Selective site deuteration on the sugar ring as an efficient marker of conformation in nucleosides: the C-D stretching mode of the (2'-R)--2'-deoxyuridine and its 3',5'-O-(1,1,3,3-tetraisopropyldisiloxan-1,3-diyl)-derivative

A uridine specifically deuterated on the deoxyribose ring at the C2', and the same compound in a more rigid form, due to a chemically fused ring (between C3' and C5'), have been synthesized.By NMR, the coupling constants J_1'-2' and J_3'-4'<
