2'-O-Methoxymethyluridine was synthesized under mild conditions using
N-iodosuccinimide (NIS) activation of a 2'-methoxythiomethyl function
in presence of methanol. Oligoribonucleotides containing such modified
uridine residues had slightly decreased duplex stability when compare
d with full RNA duplexes. No substantial increase in stability towards
snake venom phosphodiesterase (SVPD) was observed.
