ABSTRACT:
The present invention provides an improved method of synthesizing 2'-O--R substituted pyrimidine mononucleosides. The method comprises reacting an anhydropyrimidine with magnesium alkoxide in the corresponding alcohol at elevated temperatures to directly produce the 2'-O--R substituted pyrimidine nucleoside product. The method advantageously eliminates several steps from prior art methods, thereby reducing the time and cost of synthesis and increasing the yield of final product.
