Abstract

The two ribo-configured nucleosides 1-(3-C-allyl-2-O-methyl-beta-D-ribo-pentofuranosyl)thymine 3 and (1S,5R,6R,8R)-5-hydroxy-6-(hydroxymethyl)-1-methoxy-8-(thymin-1-yl )- 2,7-dioxabicyclo[3.3.0]octane 6 have been transformed into their corresponding phosphoramidites, 5 and 8 respectively, and used as building blocks for the synthesis of modified oligonucleotides. The oligonucleotides were shown to hybridize with decreased binding affinity towards complementary single stranded DNA and RNA.
