In the title compound, C(16)H(14)N(4)O(2)S, the plane of the indole ring is twisted by 70.4 (2)° with respect to the plane of the azidomethyl- substituent. As a result of the electron-withdrawing character of the phenyl-sulfonyl groups, the N-C bond lengths are slightly longer than the anti-cipated value of approximately 1.355 Å for an N atom with a planar configuration. The indole ring is esse...

A series of substituted ethyl 1-[(tert-butoxycarbonyl)amino]-2-methyl-5- (1-methyl-1H-indol-3-yl)-4-[(1-methyl-1H-indol-3-yl)carbonyl]-1H-pyrrole-3-carboxylates were prepared in excellent yields (82-98%) by one-pot reactions between β-dicarbonyl compounds 12a-e and 1,2-diaza-1,3-diene (DD) 13. Derivatives 10a,c-e, deazaanalogues of the bis-indole alkaloid topsentin, screened by the National Can...

In the title compound, C(17)H(14)N(2)O, the dihedral angle between the indole ring system and the phenyl ring is 64.48 (7)°. The crystal packing features weak C-H⋯π inter-actions.

In the title compound, C(16)H(12)N(2), the dihedral angle between the indole ring system and the pendant phenyl ring is 64.92 (5)°. The crystal packing features aromatic π-π stacking [centroid-centroid separation = 3.9504 (9) Å] and C-H⋯π inter-actions.

The title compound, C(13)H(14)OS, crystallizes with two independent mol-ecules in the asymmetric unit. The unit cell contains three voids of 197 Å(3), but the residual electron density (highest peak = 0.24 e Å(-3) and deepest hole = -0.18 e Å(-3)) in the difference Fourier map suggests no solvent mol-ecule occupies this void. The crystal structure is stabilized by π-π inter-actions between the ...

A series of 2-pyrazolines 5-9 have been synthesized from α,β-unsaturated ketones 2-4. New 2-pyrazoline derivatives 13-15 bearing benzenesulfonamide moieties were then synthesized by condensing the appropriate chalcones 2-4 with 4-hydrazinyl benzenesulfonamide hydrochloride. Ethyl [1,2,4] triazolo[3,4-c][1,2,4]triazino[5,6-b]-5H-indole-5-ethanoate (26) and 1-(5H-[1,2,4]triazino[5,6-b] indol-3-yl...

In the title compound, C16H18ClN3O, the cyclo-hexane ring adopts a distorted chair conformation. In the crystal, pairs of mol-ecules are linked by N-H⋯O hydrogen bonds into inversion dimers, forming R 2 (2)(10) ring motifs. These dimers are connected through C-H⋯N hydrogen bonds into chains along the a axis, forming layers parallel to (101).

In the title compound, C(16)H(13)NO(3)S, the sulfonyl-bound phenyl ring forms a dihedral angle of 84.17 (6)° with the indole ring system. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. The crystal structure exhibits weak inter-molecular C-H⋯O hydrogen bonds and π-π inter-actions between the five- and six-membered rings of the indole group [centroid-centroid distance = 3.68...

In the title compound, C(15)H(12)INO(2)S, the sulfonyl-bound phenyl ring forms a dihedral angle 82.84 (9)° with the indole ring system. The mol-ecular structure is stabilized by a weak intra-molecular C-H⋯O hydrogen bond. The crystal structure exhibits weak inter-molecular C-H⋯π inter-actions and π-π inter-actions between the indole groups [centroid-centroid distance between the five-membered a...
