The synthesis of 1-deazauridine 5'-nionophosphate (la) and 2'-deoxy-l-deazauridine 5'- monophosphate (lb) requires the formation of a CC glycosyl linkage between the pyridine portion and C1 of the respective sugar. Appropriate protection of the oxygen functions of the sugar and the pyridine would permit the use of a route involving alkylation of the protected halosugar by the pyridine derivative. Successful application of this approach has been ...
