Gas chromatographical determination of 5-hydroxy-3-methylindole in human urine [PDF]

, 1977
5-hydroxy-3-methylindole was first found by Spatz, Spatz, and Fischer in the urine of patients with centrencephalic epilepsy in 1972. I have determined this substance in human urine by gas chromatography with an electron capture detector (ECD).

‐Methylindole

, 2022
The synthesis of step-growth polymers by photoinduced methods is a challenging issue in synthetic chemistry. Here, we report a single component near UV responsive photopolymerization system for step-growth polymerization of N-methylpyrrole (MPyr) and N ...

3-Methylindole-Based Tripodal Tetraphosphine Ruthenium Complexes in N2 Coordination and Reduction and Formic Acid Dehydrogenation

Inorganics, 2017
The ruthenium(II) complexes RuCl2L1H, RuCl2L1CF3, RuCl2L1OMe and RuCl2L2H were synthesized from [Ru(η6-benzene)Cl(μ-Cl)]2 and the corresponding tripodal tris-3-methylindolephosphine-based ligands L1H, L1CF3, L1OMe, and L2H.

Cationic Sulfonium‐Based Tripodal Ligand and Its Rh(I) Complexes

Chemistry – A European Journal, Volume 32, Issue 30, 13 August 2026.
We report a cationic EP3‐type tripodal ligand based on an aromatic sulfonium cation (E = S+) along with a series of its Rh(I) complexes. Structural, spectroscopic, electrochemical, and computational analyses of these complexes compared to isostructural analogs (E = Si− or P) reveal pronounced electron density depletion at Rh in the sulfonium congener ...

Electrochemical polymerization and spectroscopic investigation of 2-methylindole

, 2008
Synthesis of poly (2-methylindole) (P2MI) was achieved by direct anodic oxidation of 2-methylindole in LiClO4/acetonitrile solution. The P2MI film was generated potentiodynamically between 0.00 V and +1.80 V (vs. Ag/AgCl, saturated KCl). The oxidation of

Azolyacetones as Precursors to Indoles and Naphthofurans Facilitated by Microwave Irradiation with Simultaneous Cooling

Molecules, 2009
Phthalimide reacted with phenacyl bromide under microwave irradiation to yield phenacyl isoindolidene-1,3-dione (3b), while 3a reacted with phenylhydrazine to yield the phenylhydrazone 4 that was readily converted into indoylphthalimide 8.

The effect of lung concentrations of glutathione and vitamin E on the pulmonary toxicity of 3-methylindole

, 1988
The relative roles of tissue glutathione and vitamin E concentrations in the pneumotoxicity of 3-methylindole were studied. Thirty-two goats were divided into four groups and pretreated with (i) vitamin E + cysteine, (ii) vitamin E + diethylmaleate ...
