Synthesis and pairing properties of 3′-deoxyribopyranose (4′ → 2′)-oligonucleotides ('p-DNA')

Ackermann, Damian,Pitsch, Stefan

, p. 1443 - 1462 (2007/10/03)

The preparation and the pairing properties of the new 3′-deoxyribopyranose (4′ → 2′)-oligonucleotide (=pDNA) pairing system, based on 3′-deoxy-β-D-ribopyranose nucleosides is presented. D-Xylose was efficiently converted to the prefunctionalized 3-deoxyri
