1-(2-Aminoethyl)-3-(arylsulfonyl)-1H-indoles as novel 5-HT6 receptor ligands
摘要:
Novel 1-(2-aminoethyl)-3-(arylsulfonyl)-1H-indoles were prepared. Binding assays indicated they are 5-HT6 receptor ligands, among which N,N-dimethyl-N-{2-[3-(1-naphthylsulfonyl)-1H-indol-1-yl]ethyl}amine 8t and N-methyl-N-{2-[3-(1-naphthylsulfonyl)-1H-indol-1-yl]ethyl}amine 8u showed high affinity for 5-HT6 receptors with K-i = 3.7 and 5.7nM, respectively.

as a model reaction because it meets key criteria, such as the wide range of substituents that can be present on the nitrobenzene ring, a low sensitivity to steric hindrance, and in particular the possibility of ensuring conditions in which the overall relative rates of reaction in competitive experiments are equal to the relative rates of nucleophilic addition. The values of relative rates of addition

Reactions of Nitroheteroarenes with Carbanions: Bridging Aromatic, Heteroaromatic, and Vinylic Electrophilicity
reactive than nitrobenzene. Among the five-membered heterocycles 2-nitrothiophene is the most active followed by nitroimidazoles and 4-nitropyrazole. Nitropyrroles are the least electrophilic nitroheteroarenes with reactivities comparable to nitrobenzene. Quantum chemically calculated methyl anion affinities (B3LYP/6-311G(d,p)//B3LYP/6-31G(d)) of the nitroarenes correlated only moderately with the partial
Indoles having an ester functionality in the 3-position were prepared from 2-(2-nitrophenyl)propenoic acid derivatives via a palladium-catalyzed reductive N-heteroannulation using carbon monoxide as the ultimate reducingagent. The starting materials were prepared either by a Stille coupling of 2-halo-1-nitrobenzenes with ethyl 2-(tributylstannyl)-2-propenoate or by vicarious nucleophilic substitution
