Figure 1. Structural constraints in (SC5′, RP) α,β-D-CNA TT.

Figure 1

Left: the six backbone torsion angles (labelled α to ζ) of nucleic acids. Middle: the α,β-D-CNA TT dinucleotide in which α and β are stereocontrolled by a dioxaphosphorinane ring structure. Right: superimposition of the X-ray crystallography structure of unmodified TpT (black) [40] and NMR structure of (SC5′, RP) α,β-D-CNA TT (gold).
