Abstract
Disclosed are novel bifunctional nucleoside analogs and oligonucleosides of 3-4 bases (trimers and tetramers) and longer containing at least two consecutive internucleoside linkages of two carbon-one nitrogen atom or two carbon-one oxygen atom (3'-NCC-5', 3'-CNC-5', 3'-OCC-5') internucleoside linkages. The bifunctional nucleosides are useful for preparing the trimers and tetramers, which, in turn, are useful, together with the nucleosides, in preparing oligonucleosides as well as chimeric oligonucleotide analogs, preferably antisense oligonucleosides and oligonucleotide analogs, of 6 to about 60 bases having at least two consecutive internucleoside linkages of two carbon atoms and one nitrogen atom or 2 carbon atoms and one oxygen atom in the oligonucleoside backbone.
