(±)-trans-5-Benzoyl-2-(1H-indol-3-yl)-4-phenyl-4,5-dihydro-furan-3-carbonitrile

Crystal structure of 5-benzoyl-2,4-di-phenyl-4,5-di-hydro-furan-3-carbo-nitrile

In the title compound, C24H17NO2, the carbonyl O atom of the benzoyl group is cis with respect to the furanyl O atom, and the associated O-C-C-O torsion angle is 4.62 (19)°. The puckering of the dihydro-furan ring is close to twisted ((4) T 5), with parameters Q = 0.1856 (16) Å and φ = 313.5 (5)°. Mol-ecules are inter-connected via a C-H⋯N and a C-H⋯O hydrogen bond, leading to layers parallel to the (200) plane and characterized by R 4 (4)(28) and R 4 (4)(36) graph-set motifs. The furan O atom does not participate in inter-molecular hydrogen bonding. The crystal lattice encompasses a solvent-accessible void of 24.7 (8) Å(3).

5-Benzoyl-2-(1H-indol-3-yl)-4-[4-(propan-2-yl)phenyl]-4,5-dihydrofuran-3-carbonitrile

In the title compound, C₂₉H₂₄N₂O₂, the hydrofuran ring is twisted with puckering parameters Q = 0.1553 (16) Å and ϕ = 305.0 (6)°. In the crystal, the graph-set motifs of the inter­action pattern are an R₂²(16) motif involving dimers through N—H⋯N hydrogen bonds across centres of inversion and a C(6) motif through C—H⋯O hydrogen-bond between glide-related mol­ecules. Together, these generate [101] ladder-like chains.
