[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
