“…Variations in 31 P phosphate chemical shifts have been shown to correlate with mean P–O bond lengths37,38 and O–P–O bond angles 39. However, the phosphono 31 P chemical shifts in this risedronate series appear to depend more on how water is incorporated into the solid form rather than P–O bond lengths and angles that showed no consistent trends.…”

“…However chemical (Gorenstein et al 1984) and heteronuclear NMR (Frey et al 1985) methods have recently been reported for assigning the phosphorus resonances and simulation methods have been employed to extract the relevant 1 H-31 P coupling constants from the experimental spectra (Chazin et al 1986). Estimates of the dihedral angle dependence of the coupling and of the phosphorus chemical shift (Gorenstein, 1983), and possibly even heteronuclear cross-relaxation rates, should enable the actual phosphodiester conformation to be determined in the future.…”

There has been a surge of recent interest, reflected by a sharp increase in the number of publications, in the area of high-resolution nuclear magnetic resonance (NMR) studies of DNA. The goal of many of these studies is to monitor the structure of biologically important DNA sequences directly in solution; the impetus for such studies was the realization, from early single-crystal X-ray structures, that nearest-neighbor context effects are a major determinant of local structure in short double-helical DNAs (Dickerson & Drew, 1981; Dickerson, 1983). Thus, instead of the previously assumed regular averaged structure of the double helix derived from fibre diffraction analysis, the more interesting concept emerged that specific sequence-dependent distortions from ‘classical’ DNA structure might be responsible for the recognition of such sequences by a variety of ligands such as repressors, polymerases, drugs, etc.

“…Assignment of phosphorus resonances in compound 7 was made on the basis of the influence of substituents: electron acceptors at the α-carbon are known to induce high-field shifts of the 31 P nucleus. 17 In addition, phosphoryl oxygen at the axial phosphorus (at C-3) can form an intramolecular hydrogen bond with the hydroxyl, and this can result in a low-field shift of the phosphorus nucleus. 18 Compound 7 is formed from the corresponding monophosphonate 4, therefore the primary monophosphonate is drawn as isomer 4a with the same configuration of the secondary methyl group.…”
