new modular synthesis of diverse 2,4-disubstitutedpyrimidin-5-ylC-2′-deoxyribonucleosides by sequentialregioselectivereactions of 2,6-dichloropyrimidin-5-yl C-nucleoside was developed. The intermediate was prepared by the Heck coupling of 2,6-dichloro-5-iodopyrimidine with glycal followed by desilylation and reduction. Its mild nucleophilic substitutions or cross-coupling reactions proceeded regioselectively
