Elemental sulfur accelerated the reactivity of the 3-position of indole for the construction of chromeno[2,3-b]indoles

An intermolecular cross-cyclization between salicylaldehydes and indoles for the preparation of chromeno[2,3-b]indole derivatives was successfully developed by using elemental sulfur as the promoter and oxidant. Various chromeno[2,3-b]indoles can be prepared using indoles and salicylaldehydes bearing different functional groups. The preliminary mechanistic investigations demonstrated that elemental sulfur not only acted as an additional oxidant but also facilitated the reactivity of the 3-position of indole.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 306-08-1. Safety of Homovanillic Acid.

Synthesis of 3-(Trifluoromethyl)indoles by Oxidative Cyclization of o-Sulfonamido-alpha-(trifluoromethyl)styrenes

3-(Trifluoromethyl)indoles were successfully synthesized by cyclization through intramolecular oxidative C-H/N-H coupling of alpha-(trifluoromethyl)styrenes bearing a sulfonamido group at the ortho-position. On treatment with cerium (IV) ammonium nitrate (CAN) in tert-butyl alcohol, o-sulfonamido-alpha-(trifluoromethyl)styrenes underwent oxidative cyclization assisted by microwave irradiation to afford the corresponding 3-trifluoromethylated indoles. By using this method, 3-(trifluoromethyl)indoles bearing various substituents were obtained in high yields. We assumed that the reaction proceeded through (i) radical 5-endo-trig cyclization of intermediary aminyl radical cations, generated by one-electron oxidation of the sulfonamide nitrogen, and (ii) subsequent another one-electron oxidation, followed by deprotonation.

Polyethylene Glycol (PEG-400): A Green Reaction Medium for One-Pot, Three Component Synthesis of 3-Substituted Indoles under Catalyst Free Conditions

A catalyst-free, cost-effective and environmentally friendly protocol for the synthesis of 3-substituted indoles via a one-pot multicomponent condensation reaction of indole, C-H activated acids and aromatic aldehydes in polyethylene glycol 400 (PEG-400) as a reaction medium and reaction promoter has been developed.

Subcellular discriminated distribution under diverse apoptosis phase using a two-photon active probe with indole moiety

Subcellular organelles play critical roles in the process of apoptosis. Fluorescent probes that specifically target different organelles during cell death processes to monitor cell viability has important implications. In this work, two D(donor)-pi-A(acceptor) configuration molecules (A1 and A2) with considerable two-photon absorption cross section in the near infrared region have been rational designed and synthesized. Of note, the obtained two probes could target different organelles in living and fixed cells, respectively. The reasons for different organelles targeting ability of A1 and A2 are discussed in our work. It provides a promising platform for real-time monitoring of cell mortality under subcellular level.

Chlorination of 2-substituted 1-hydroxyindoles

Chlorination of 1-hydroxyindole-5,6-dicarbonitriles and 1-hydroxypyrrolo[3,4-f]indole-5,7(1H,6H)-diones with N-chlorosuccinimide afforded previously unknown 3,3-dichloro-3Hindole 1-oxides instead of the expected 3-chloro-1-hydroxyindoles. The latter, however, were prepared in good yields by treatment of the above 3,3-dichloro-3H-indole 1-oxides with piperidine in ethanol. Reduction of 3,3-dichloro-5,6-dicyano-3H-indole 1-oxides with Zn in AcOH yielded the corresponding 3-chloroindole-5,6-dicarbonitriles.

Effect of environmental temperature, floor type and breed on skatole and indole concentrations in fat of females, immuno-castrated and entire males

The present study was divided in two different trials. The aim of the first trial was to determine if the thresholds of detection of skatole and indole are achieved in females and in males vaccinated against the GnRF housed in two different type of floors and subject to control or high environmental temperatures. The aim of the second trial was to assess the effect of sire (Duroc crossbreed and Pietrain crossbreed) and heat stress on the concentration of skatole and indole in entire males. In the first trial, the animals subjected to heat stress on a concrete floor were found to be dirtier and to present higher skatole and indole concentrations than did animals from the control treatment in 100% slatted floors. In the second trial, although the animals were dirtier when subjected to high temperatures, no effect of the temperature was found in skatole/indole concentrations. The Duroc pigs were dirtier and had higher skatole and indole concentrations than did Pietrain pigs. It is concluded that even females or vaccinated males can reach values of skatole/indole close to the thresholds of sensory detection under conditions of dirtiness and heat stress. However, the relationship between heat, dirtiness and skatole/indole concentrations in fat were not confirmed in trial 2 using entire males.

Copper-catalyzed tandem annulation/enol nucleophilic addition to access multisubstituted indoles

A method to access various multisubstituted indoles from propargylic alcohols and readily available enol nucleophiles by copper-catalyzed tandem annulation/enol nucleophilic addition has been developed.

The fused heterocyclic compounds, pyrrolo[1,2-a] indoles, could be afforded by further transformation of the products. The allyl cation intermediate may be involved in the mechanism.
