A convergent and general approach to synthesizing 2′-O-Methylpyrimidine ribonucleosides 4a-e, 6,7 on a multigram scale is described which begins with an improved procedure for making larger quantities of 2-O-methyl-1,3,5-tri-O-benzoyl-α-D-ribose. The sugar was reacted with the desired silylated pyrimidines at room temperature under Vorbrüggen conditions. The crude products contained less than 10% of

For large scale preparation of pyrimidine ribonucleosides, the intermediate 2-O-methyl-(or ethyl)-1,3,5-tri-O-benzoyl-.alpha.-D-ribose can be prepared using a diazomethane (or diazoethane) reaction that is controlled via an inert solvent transferring system. This transfer system allows for large scale preparations of the pyrimidine ribonucleosides.
