In the title compound, C30H22N2O7S2, the configuration about the propene C=C bond is E. The indole unit is essentially planar, with a maximum deviation of 0.031 (3) Å. The dihedral angle between the planes of the phenyl rings of the two phenylsulfonyl groups is 80.95 (19)°. The central prop-2-ene-1-one group is oriented at a dihedral angle of 44.26 (11)° with respect to the nitrophenyl ring and at 39.24 (8)° with respect to the indole unit. The S atoms are in a distorted tetrahedral configuration. In the crystal, molecules are linked into centrosymmetric dimers via pairs of C—HO hydrogen bonds with an R22(24) graph-set motif. The crystal structure is stabilized by further C—HO interactions. Short intramolecular C—HO contacts result in several S(6) rings.

In the title compound, C18H18O2, the methyl acrylate substituent adopts an extended E conformation with all torsion angles close to 180°. The mean plane of the acrylate unit and the phenyl ring are approximately orthogonal to each other, making a dihedral angle of 81.40 (6)°. The position of the carbonyl group with respect to the olefinic double bond is typically S-trans. The crystal packing is stabilized by intermolecular C—Hπ interactions.

In the title compound, C14H10N2O2S, the benzothiazole and quinazoline ring systems are essentially planar with maximum deviations of 0.0127 (16) and 0.1588 (15) Å, respectively, and make a dihedral angleof 3.02 (5)°, which shows that the entire molecule is almost planar. The O atoms deviate from the benzothiazole ring system by 1.2231 (14) and −1.1989 (15) Å. The crystal packing features non–classical C—HO hydrogen bonds and is further consolidated by π–π interactions [centroid–centroid distances = 3.7568 (8) and 3.8848 (9) Å].
