2′-Deoxynucleoside-3′-O-(4-nitrophenyl) phosphoranilidates (e.g., 2), prepared by the action of O-(4-nitrophenyl)N-phenylphosporamidochloridate (1) on alcohols, are converted into the corresponding 4-nitrophenyl phosphate esters (e.g., 3) or P-chiral 4-nitrophenyl phosphorothioate esters (e.g., 4) by treatment with NaH–CX2(X = O or S).

Internucleotidelinkage can be made readily by reaction of -unprotected nueleosides and phosphorochloridates or -nitrophenyl phosphates by the assistance of Grignard reagents.

been blocked as the benzyl carbamates, and 2'-deoxyguanosine has been blocked as its 2-N-(benzyloxycarbonyl)carbamate and 6-O-benzyl ether. These blocked nucleosides have been incorporated into an efficient oligodeoxyribonucleotide synthetic scheme, and the resulting oligomer has been successfully deblocked by using transfer hydrogenation. The deblocking conditions result in no reduction of the pyrimidine
