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].

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...
