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.

Development of a Novel, Highly Efficient Halide-Catalyzed Sulfenylation of Indoles
摘要:
The reaction of a variety of indoles with N-thioalkyl- and N-thioarylphthalimides to produce 3-thioindoles is reported. Catalytic quantities of halide-containing salts are crucial to the success of this reaction. This highly efficient reaction provides sulfenylated indoles from bench-stable, readily available starting materials in good to excellent yields.
An efficient and convenient palladium-catalyzed C–H bond oxidative sulfenylation of indoles and related electron-rich heteroarenes with arylboronicacids and elementalsulfur has been described. This procedure provides a useful and direct approach for the assembly of a wide range of structurally diverse 3-sulfenylheteroarenes with moderate to excellent yields from simple and readily available starting
