Amide-Modified Oligonucleotides with Preorganized Backbone and Furanose Rings: Highly Increased Thermodynamic Stability of the Duplexes Formed with their RNA and DNA Complements

The amide backbone modification C3′-CH2-CONH-C5′ has been further modified by introducing a methyl at C5′, either in R or in S configuration. Only the S stereoisomer can adopt the required geometry to fit into a duplex with complementary RNA. A
