Sažetak
In this paper, inter- or intra-molecular induced oxazolidine ring opening of two bicyclic nucleosides during recrystallisation are presented. The structures of these two compounds, azide derivative 2 and -NHBz derivative 3, as well as bicyclic O-trityl derivative 1, have been determined by single crystal X-ray diffraction method. The aim of this work was to understand the influence of structural differences of dihydrothymines on their supramolecular assemblies. In the crystal structure of 1, which crystallized with one ethanol molecule in the asymmetric unit, O-H•••N and C-H•••O intermolecular hydrogen bonds form two-dimensional network. One C-H•••Pi interaction extends two-dimensional network into three-dimensional. Supramolecular structure of 2 is a three-dimensional network formed by N-H•••O, O-H•••O, C-H•••N and C-H•••O hydrogen bonds. Compound 3 crystallized with two independent molecules and two water molecules in the assymetric unit and displays the greatest number of intermolecular interactions. Interestingly, although N-H•••O, O-H•••N, O-H•••O and C-H•••O hydrogen bonds are formed, as well as two C-H•••Pi interactions, the result is only a two-dimensional network.
