Rerefinement of (μ-1,7,11,17-tetraoxa-2,6,12,16-tetraazacycloeicosane-κ4N1,N17:N7,N11)bis[dichlorozinc(II)]. [Dataset] (2002)

This rerefinement of the title compound, [Zn2Cl4(C12H28­N4O4)], based on the original intensity data, differs from the original only in the exchange of the NH and O moieties of the oxa­aza-macrocycle, resulting in a dramatic improvement in the R fact...

[Dataset] Acta crystallographica section C: crystal structure communications [online], 51(7), pages 1347-1350. Available from: https://doi.org/10.1107/s0108270195000096

The title compound, C15H19N3O7 (P), crystallizes with two molecules in the asymmetric unit which differ in sugar and oxazino ring puckering; both occur as the imino tautomer and form P;P wobble base pairs. The supporting information for the published... Read More about 6-(3,5-Di-O-acetyl-β-D-2-deoxyribofuranosyl)-3,4-dihydro-8H-pyrimido[4,5-c][1,2]oxazin-7(6H)-one. [Dataset].

MOORE, M.H., VAN MEERVELT, L., SALISBURY, S.A., KONG THOO LIN, P. and BROWN, D.M. 1995. Direct observation of two base-pairing modes of a cytosine-thymine analogue with guanine in a DNA z-form duplex: significance for base analogue mutagenesis. [Dataset]. Hosted on Worldwide Protein Data Bank (wwPDB) [online], 223D. Available from: https://doi.org/10.2210/pdb223d/pdb

The pyrimidine nucleobase analogue 6H,8H-3,4-dihydropyrimido[4,5-c]-[1,2]oxazin-7-one (P) is a mimic both of cytosine and thymine, since it can form stable hydrogen-bonded base-pairs with either guanine or adenine. To investigate the geometric proper...
