The title molecule, C 27 H 36 N 2 O 6 Si, contains a pair of fused tetrahydrofuran rings, symmetrically substituted by p-nitrophenyl groups at centres of R chirality. The crystal structure is composed of dimers interacting through %-stacking to form columns.
The title compound, C~26~H~26~N~2~O~7~, is a thiamidine derivative. Geometric parameters are in the usual ranges. The crystal packing is stabilized by a classical N—H...O hydrogen bond, several weak C—H...O hydrogen bonds and a π–π stacking interaction.
In the title compound, C 14 H 13 NO 5 , the C atom between the benzene and oxazolone rings displays a distorted trigonal bonding geometry. The oxazolone and aromatic rings are approximately coplanar.
