(E)-3-(2-Nitro­phen­yl)-1-{1-phenyl­sulfonyl-2-[(phenyl­sulfon­yl)meth­yl]-1H-indol-3-yl}prop-2-en-1-one

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—H...O hydrogen bonds with an R₂²(24) graph-set motif. The crystal structure is stabilized by further C—H...O inter­actions. Short intra­molecular C—H...O contacts result in several S(6) rings.

rac-Diethyl 5-oxo-2-[(2,4,4-trimethyl­pentan-2-yl)amino]-4,5-dihydro­pyrano[3,2-c]chromene-3,4-dicarboxyl­ate

The title compound, C₂₆H₃₃NO₇, comprises a racemic mixture of asymmetric mol­ecules containing one stereogenic centre. The dihedral angle between the mean planes of the fused pyran ring and the coumarin ring system is 8.12 (14)°. The mol­ecular structure features a short N—H...O contact, which generates an S(6) ring motif. The crystal packing are stabilized by C—H...O inter­actions.
