Two new useful methods for the preparation of diol 1 starting from available compounds are described. Separation of the two enantiomers entails resolution of racemic diol 1 via the corresponding diastereomeric N-methylated phosphorothioamidates. Their separation by recrystallization followed by redu

✦ Synopsis
The title compound, C 14 H 10 N 4 O 10 , was obtained by nitration of 6,6 0 -dimethoxy-2,2 0 -dinitro-1,1 0 -biphenyl in the presence of an excess of fuming nitric acid. In the molecule, the dihedral angle between the two benzene rings is 89.9 (2) . In the crystal structure, molecules are connected by weak intermolecular C-HÁ Á ÁO hydrogen bonds to form one-dimensional chains.
