The synthesis of 7-propynyl-, 7-iodo- and 7-cyano-7-deaza-2-amino-2'-deoxyadenosines is described. The nucleosides were synthesized, functionalized into the phosphoramidites and incorporated into oligodeoxynucleotides. Spectroscopic melting experiments against complementary RNA showed increases of 3-4 degreesC per modification for single substitutions and smaller increases per incorporation for multiple substitutions relative to unmodified control sequences. The 7-propyne and 7-iodo nucleosides… Expand
