Thymidine (2) and 5-methyl-2′-O-(t-butyldimethylsilyl)uridine (3) deuterated at the C3′-position were prepared with complete stereocontrol via NaB2H4 reduction of a 3-oxoribose derivative (5). Utilization of benzyl protectinggroups in the deuterated glycosidation substrate facilitates the synthesis of ribonucleosides and 2′-deoxyribonucleosides with minimal protectinggroup manipulations.

[reaction: see text] 2'-Deoxy-3'-deutero pyrimidines have been synthesized in high yields and incorporated into deoxyoligonucleotides using standard phosphoramidite chemistry. A key synthetic step is a stereospecific reduction of 3'-keto nucleosides using sodium triacetoxyborodeuteride to give 3'-deuterated thymidine and 2'-deoxy uridine nucleosides. Conversion of the corresponding phorphoramidites
