Description	A new modular synthesis of diverse 2,4-disubstituted pyrimidin-5-yl C-2'-deoxyribonucleosides by sequential regioselective reactions of 2,6-dichloropyrimidin-5-yl C-nucleosides 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 Fe-catalyzed cross-coupling with MeMgCl proceeded regioselectively at position 4, whereas at elevated temperatures or with excess of MeMgCl, double substitution occurred. The 2-chloro-4-substituted intermediates undergo another substitution or coupling to afford 2,4-disubstituted derivatives.
