3-Carboxy-1-sulfopyridin-1-ium chloride ([CPySO3H]+Cl-) as a novel ionic organocatalyst for thecondensation of aldehydes and 2-methylindole to synthesize bis(2-methyl-1H-indole) derivatives inacetonitrile at room temperature has been developed. Some tetrakis (2-methyl-1H-indole)derivatives have also been synthesized by the reaction of 2,2'-(butane-1,4-diylbis(oxy))dibenzaldehyde and 2-methylind...

In a screening for antifungal metabolites, two indole compounds of mixed biogenesis, 1H-indole-3-carboxylic acid, 1-(1,1-dimethyl-2-propenyl) methyl ester and 1H-indole-3-carboxylic acid, 1-(2,3-dihydroxy-1,1-dimethylpropyl) methyl ester were isolated from a culture of the basidiomycete Aporpiums caryae. The structural elucidation of these compounds was accomplished by spectroscopic methods.

Methyl 9-(1-methyl-1H-indol-3-yl)-9-oxononanoate was synthesized using Friedel–Crafts acylation between N-methyl indole and methyl 9-chloro-9-oxononanoate. The structure of the newly compound elucidated 1H-NMR, 13C-NMR, NOESY-1D, ESI-MS, FT-IR, UV-Vis spectroscopy.

Headspace solid-phase microextraction (HS-SPME) and ultrasonic solvent extraction (USE), followed by GC-MS/FID, were applied for monitoring the nectar (NE)/honey-sac (HoS)/honey (HO) pathways of the headspace, volatiles, and semi-volatiles. The major NE (4 varieties of Citrus unshiu) headspace compounds were linalool, α-terpineol, 1H-indole, methyl anthranilate, and phenylacetonitrile. Correspo...

<p>In this research, we have described a facile and user-friendly protocol for the formation of 2((1H-Indole-3yl)(Phenyl)methyl)malononitrile derivatives using recoverable efficient TiO2 nanocatalyst. This is simple incredibly synthesis novel derivatives. Nanoscale used as catalyst. Since TiO<sub>2 </sub>has more surface area easily binds with active site reactive molecule ini...

Indole moiety is well-known as a superlative framework in many natural products and synthetic pharmaceuticals. Herein, we report an efficient procedure to synthesize series of functionalized 2-methyl-1H-indole-3-carboxylate derivatives from commercially available anilines properly by different electron-withdrawing -donating groups through palladium-catalyzed intramolecular oxidative coupling. T...

The title compound, C26H21F3N2, was prepared by the palladium-catalysed reaction of (2,2,2-tri-fluoro-eth-yl)benzene with 1-methyl-1H-indole. The dihedral angle between the planes of the indole-ring systems is 52.13 (6)° and the N-methyl groups point away from each other. Three short intra-molecular C-H⋯F contacts are observed.
