Abstract

5,6-Dialkylated uridine derivatives were conveniently synthesized in 5 steps starting from 2′,3′-O-isopropylideneuridine (1) in a 43% overall yield. The key reaction is a novel acid catalyzed cyclization reaction of 6-(4-butanal)-2′,3′-O-isopropylideneuridine.

Abstract

H 2 OX + is one of the prominent but doubtful species suggested in recent years to explain the electrophilic substitution in halogenations of organic substrates. The present studies are aimed at revealing the role of this hypothetical species in such reactions on the basis of related kinetic and conductance data and also on the basis of equilibria affecting the formation of H 2 OX + in aqueous solutions.
