Aminolysis of 2′-Deoxyinosine Aryl Ethers: Nucleoside Model Studies for the Synthesis of Functionally Tethered Oligonucleotides

Abstract
Several O6-aryl-2′-deoxyinosines were synthesized and found to undergo conversion to N6-substituted-2′-deoxyadenosines upon treatment with aqueous amines. The kinetics for reaction of these nucleosides with various amines suggests that O6-phenyl- and O6-(p-nitrophenyl)-2′-deoxyinosine are suitable “convertible nucleoside” precursors for the site-specific introduction of functionally tethered 2′-deoxyadenosines into DNA.
