The copper-catalyzed sulfenylation of indoles with aryl iodide and sulfur powder has been investigated both experimentally and theoretically. This protocol provides a direct and facile approach to prepare 3-sulfenylindoles with moderate to excellent yields and good functional-group tolerance. The in-situ IR analysis provided evidence for that NaOAc could promote the synthesis of diphenyl disulfide by the coupling of aryl iodide and sulfur powder. According to DFT calculations, the coupling pathway involving the intermediate N-methyl-3-iodoindole is more favored than the direct coupling by the C-H activation of indole. The N-methyl-3-iodoindole was identified as a crucial intermediate in the catalytic cycle.

Herein, we unveil the first visible-light-mediated alkenylation reaction of indoles. The reaction follows a denitrative radical pathway where beta-nitrostyrenes have been utilized as the alkene precursors for the C3-styrenylation of indoles under visible-light irradiation to afford biologically and synthetically important 3-alkenylindoles. High regioselectivity, absence of any photocatalyst, metal, external oxidant, acid or base, and the use of visible light and air as inexpensive clean reagents are the key highlights of the developed method.

In a document, author is Wang, Jian, introducing its new discovery. Product Details of 19767-45-4.

The first example of a dearomative palladium-catalysed isocyanide insertion reaction has been developed using functionalized isocyanides as the reaction partner of N-(2-bromobenzoyl)indoles. The imidoyl-palladium intermediate generated by tandem indole double bond/isocyanide insertion reactions could be trapped by intramolecular functional groups such as the C(sp(2))-H bond and alkenes, affording diversified indoline derivatives bearing C3 imine-containing heterocycles. The dearomative aryl/cycloimidoylation of indoles proceeded smoothly in good to excellent yields with a wide functional group tolerance.

This study describes the first carbon centered radical cyclization of N-propargyl indoles involving decarboxylation of alpha-keto acids in the presence of an Ag-catalyst. The present cascade carbon-carbon bond formation reactions provide C-acylated pyrrolo[1,2-a]indoles in good yields (25 examples). The amount of oxidant has a profound effect on the reaction to convert either the di-acylated products using 8 equiv. of K2S2O8 or mono-acylated products using 2 equiv. of K2S2O8. N-Propargyl pyrroles are also found to be suitable for delivering the corresponding 3H-pyrrolizines.

As the growth in resistance to bacterial infection treatments poses a grave threat to global health in the 21st century, there is a constant need to explore novel antibacterial agents that have the ability to overcome drug resistance. Indole-containing alkaloids are widely distributed in nature, and a variety of indole-containing alkaloids have already been applied in clinical practice, proving that indole-containing alkaloids are fascinating and privileged scaffolds for the development of novel drugs. Moreover, indole-containing alkaloids could exert their antibacterial activity through the inhibition of efflux pumps, the biofilm, filamentous temperature-sensitive protein Z, and methicillin-resistantStaphylococcus aureuspyruvate kinase; so, indole-containing alkaloids constitute an important source of novel antibacterial agents. This review is an endeavor to highlight the advances in the development of indole-containing alkaloids with antibacterial potential, covering articles published in the recent 10 years.

The dried seeds of Aesculus chinensis Bge. var. chekiangensis (Hu et Fang) Fang, called Suo Luo Zi, have been used in traditional Chinese medicine. Nevertheless, most studies have been focused on components of less polarity fractions. In this research, twelve indoles, including six new indole glycosides (1-6) as well as six known analogs were isolated from the polar portion which has been seldom studied. This is the first description of N-glucosylated indoles obtained from the genus of Aesculus. Structures of the new compounds (1-6) were elucidated based on comprehensive interpretation of HRESIMS, 1D and 2D NMR. Additionally, the neuroprotective activities of the N-glucosylated indoles were evaluated for the first time indicating that compounds 1-5 and 9-10 exhibited moderate neuroprotective activities. Further cytotoxicity tests of isolates 1-10 on three human tumor cell lines suggested that none of these compounds were cytotoxic (IC50 > 50 mu M).
