Chimeric RNA with modified backbones: alternating methylene(methylimino) linked phosphodiester backbone oligonucleotides with 2'-OH and 2'-OMe groups.
2001
Synthesis of a novel ribo-MMI dimer with 2′-OH and 2′-OMe in 5′- and 3′-nucleosides, respectively is presented. The synthesis was accomplished by reductive coupling of 3′-deoxy-3′-C-formyluridine and 2′-O-methyl-5′-O-methylaminouridine via a thioacetal as the key intermediate for the top part of the dimer. Incorporation of ribo- MMI dimers into oligonucleotides increased binding affinity for target RNA.
