We report here the firstsynthesis of Te‐nucleoside phosphoramidites and Te‐modified oligonucleotides. We protected the 2′‐tellurium functionality by alkylation and found that the Te functionality is compatible with solid‐phase synthesis and that the Te oligonucleotides are stable during deprotection and purification. In addition, the redox properties of the Te functionalities have been explored. We

Several 2′,3′-dideoxynucleosides (ddNs) and 2′,3′-didehydro-2′,3′-dideoxynucleosides (d4Ns) are FDA-approved anti-HIV drugs. Via conveniently synthesized 2,2′-anhydronucleosides, we have developed a novel synthesis of d4Ns by discovering and applying a new telluride-mediated elimination reaction. Our experiment results show that after substitution of 2,2′-anhydronucleosides with a telluride monoanion
