1-(2-Methylbenzyl)-1H-indole-3-carbaldehyde
In the title compound, C(17)H(15)NO, the benzene ring and the indole system are almost perpendicular, making a dihedral angle of 87.82 (6)°. The crystal packing is stabilized by C-H⋯O and π-π stacking inter-actions with centroid-centroid distances of 3.592 (4) Å between the pyrrole and the benzene rings in the indole systems of neighboring mol-ecules.

متن کاملSynthesis and structure of 1-(2-bromophenyl)-2-chloro-3-(2-chloracetyl)-1H-indole
In the title indole derivative, C16H10BrCl2NO, the dihedral angle between the mean plane of the indole ring system and the mean plane of the disordered 2-bromo-phenyl ring is 77.6 (1)°. The non-H atoms of the chloracetyl group are essentially coplanar with the indole core. In the crystal, pairs of mol-ecules are face-to-face embraced via two weak C-H⋯O hydrogen bonds, forming inversion dimers w...
متن کاملSynthesis of 1-Hydroxy-2-(Prop-2'-Enyl) 9-Antrone
An efficient synthesis of the 1-hydroxy-2-(prop-2'-enyl)9-anthrone is described. Selective nitration of anthraquinone, reduction to the corresponding amine, diazotization and treatment by sulfuric acid solution afforded the 1-hydroxy-9,10-anthraquinone in good yield as the key intermediate. Reaction with allyl bromide/K2CO3 and subsequent selective reduction accompanie...
