description | The asymmetric unit of the title compound, C21H20N4O3S, contains two independent molecules. The dihedral angles between the two benzene rings are 47.6 (1) and 30.2 (1)°, the corresponding values between the p-methoxybenzene and thiadiazol rings are 12.3 (1) and 24.7 (1)°, respectively, for the two molecules. The conformations of the N—H and C=O bonds are anti with respect to each other. The enone groups show a trans configuration. The crystal structure is stabilized by N—H...O and N—H...N interactions. The absolute structure could not be determined from the X-ray data but the absolute configuration has been assigned by reference to an unchanging chiral centre in the synthetic procedure. |
