Pentopyranosyl Oligonucleotide Systems
Beta-D-Xylopyranosyl-(4 - 2 )-oligonucleotides containing adenine and thymine as nucleohases were synthesized as a part of a systematic study of the pairing properties of pentopyranosyl oligonucleotides. Contrary to earlier expectations based on qualitative conformational criteria, Beta-D-xylopyranosyl(4 - 2 )- oligonucleotides show Watson-Crick pairing comparable in strength to that shown by pyranosyl-RNA.
