Abstract The fabrication of diodes using organic semiconductors as active materials has gained wide interest, and undergone significant progress in the past few decades. A naphthalimide-indole derivative (BNIA) was synthesized through bromination acenaphthene, subsequent oxidation, finally imidation with indole-3-acetic anhydride. molecular structure characterized NMR IR spectroscopy. BNIA disp...

The hydride stretch infrared spectra of indole, indole–H2O, 3-methyl indole, 3-methyl indole–H2O, the main conformer of tryptamine ~TRA!, two conformers of N-acetyl tryptophan amide ~NATA!, and three conformers of N-acetyl tryptophan methyl amide ~NATMA!, have been recorded in the electronically excited singlet states using excited-state fluorescence-dip infrared spectroscopy. NATA and NATMA ar...

A copper-catalyzed synthesis of 2-(aminomethyl)indole through domino three-component coupling-cyclization has been developed. This reaction proceeds through Mannich-type coupling of 2-ethynylanilines, aldehydes, and secondary amines, followed by hydroamination. This indole formation was applicable to the synthesis of 4-methylene-2,3,4,9-tetrahyro-1H-pyrido[3,4-b]indoles and 5,6,7,8-tetrahydrobe...

In this article, simple, convenient synthesis of 2-aryl-1- arylmethyl-1H-1,3-benzimidazole (1,2-disubstituted benzimidazoles) via condensation of 1,2-phenylenediamine and aromatic aldehydes using SBA-Pr-SO3H as a nanoporous solid acid catalyst in green protocol was reported.

In the title compound, C(15)H(13)NO(4), the conjugated double-bond system between the two rings adopts a cis configuration and there is an intra-molecular indole-ketone C-H⋯O inter-action. The indole N-H group forms an inter-molecular hydrogen bond with a ketone O-atom acceptor, giving a chain structure along the ab direction. The O-heterocyclic ring adopts a boat conformation and makes a dihed...

In the title mol-ecule, C(24)H(17)N(3), the didhedral angles formed by the mean planes of the indole ring systems and the benzene ring are 86.44 (7) and 86.96 (7)°. The dihedral angle between the two indole ring systems is 72.08 (6)°. In the crystal, inter-molecular bifurcated (N-H)(2)⋯N hydrogen bonds link mol-ecules into sheets lying parallel to (010).

Reaction of tryptamine 1 with dimethyl -3-methoxyallylidenemalonate 2 afforded N?-[4,4-bis (methoxycarbonyl)-1,3-butadienyl] tryptamine 3 which in combination with acetylchloride and pyridine in dichloromethane gave N?, N?-[acetyl]-[(4,4-dinethoxycarbonyl) 1,3butadienyl] tryptamine 4. Treatment of 3 with sodium hydroxide afforded 2H[N-(3-indolyl) ethyl] 2-oxo-3-methoxycarbonyl-1-pyridine 5. Cy...
