EnglishThe synthesis and a preliminary evaluation of the pairing properties of ribo-cyclohexanyl nucleic acids (r-CNA) is herein reported. Incorporation of a single r-CNA nucleotide into natural duplexes did not enhance their stability, while a very high pairing selectivity for RNA was found. As deduced by comparative analysis of Tm and NMR data, a relationship between pairing selectivity and conformational preferences of the “sugar” moiety of r-CNA (and more generally of six-membered nucleic acids) was suggested.
