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...

Microwave-assisted synthesis of some novel compounds, namely, 3-(2-methyl-1H-indol-3-yl)-6-aryl-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazoles 5a,b was accomplished via bromination of 2-methyl-3-[4-(arylideneamino)-5-mercapto-4H-[1,2,4]triazol-3-yl]-1H-indoles 3a,b. Also, new [1,3,4]thiadiazoles 12a,b, [1,2,4]triazoles 15a,b and [1,3,4]oxadiazoles 19a,b, with indole moieties, were prepared by cycliz...

A simple and efficient method for the synthesis of biologically relevant 5H-benzo[4,5][1,3]thiazino[3,2-a]indoles and 5,7-dihydroisothiochromeno[3,4-b]indoles has been developed via intramolecular copper catalysed Ullmann-type C-N coupling and palladium catalysed direct arylation from the corresponding precursors 2-(2-bromobenzylthio)-1H-indole and 2-(2-bromobenzylthio)-1-methyl-1H-indole, resp...

The title compound, C(12)H(12)N(2)O(3), was synthesized by condensation of methyl amino-acetate with 3-trichloro-acetyl-indole. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains parallel to the b axis. The chains are further connected into a three-dimensional network by N-H⋯O hydrogen bonds involving the indole N atom. In the molecule, the indole skeleton is n...

The indole N-H hydrogen in the title compound, C(15)H(12)FN, does not display classical hydrogen bonding. Rather it forms an interaction with the π system of an adjacent indole, resulting in weakly inter-acting chains along the [001] direction.

The title compound, C(12)H(13)NO(4), was prepared as a precursor to an indole derivative with possible anti-mitotic properties. The mol-ecule is very nearly planar; the maximum deviation of any non-H atom from the mean plane of the indole ring is 0.120 (3) Å for each of two meth-oxy C atoms. The pairs of mol-ecules related by the inversion centre at (0,0,) are connected by two symmetry-equivale...

On the basis of N-((5-(3-(1-benzylpiperidin-4-yl)propoxy)-1-methyl-1H-indol-2-yl)methyl)-N-methylprop-2-yn-1-amine (II, ASS234) and QSAR predictions, in this work we have designed, synthesized, and evaluated a number of new indole derivatives from which we have identified N-methyl-N-((1-methyl-5-(3-(1-(2-methylbenzyl)piperidin-4-yl)propoxy)-1H-indol-2-yl)methyl)prop-2-yn-1-amine (2, MBA236) as ...

The chloroform solvate of uncarine C (pteropodine), (1'S,3R,4'aS,5'aS,10'aS)-1,2,5',5'a,7',8',10',10'a-octahydro-1'-methyl-2-oxospiro[3H-indole-3,6'(4'aH)-[1H]pyrano[3,4-f]indolizine]-4'-carboxylic acid methyl ester, C(21)H(24)N(2)O(4).CHCl(3), has an absolute configuration with the spiro C atom in the R configuration. Its epimer at the spiro C atom, uncarine E (isopteropodine), (1'S,3S,4'aS,5'...
