The acetate 30 could be condensed (Schemes 11,12 and 13) with a variety of purines (6-chloro and 6-chloro-2-fluoropurine) and pyrimidines (thymine,uracil and cytosine) to give the corresponding 2-phenylseleno-P-nucleosides in good to excellent yields in 95 to 99% anomeric purity. The 6-chloropurine condensation product 31 (Scheme 11) is a versatile intermediate, which under the appropriate conditions can be converted to inosine (32), adenosine (33), N -...
