Acylation of indoles via photoredox catalysis: A route to 3-acylindoles

A visible-light-induced synthesis of 3-acylindoles from simple indoles and α-oxo acids at room temperature has been discovered. The reaction tolerates a wide range of functional groups and gives a variety of valuable 3-acylindoles in moderate to high yields under mild conditions.

Synthetic method of indole-3-aromatic ketone derivative

The invention provides a novel method for an indole-3-aromatic ketone derivative. By using induction action of visible light, indole and aryl sulfonyl chloride and carbon monoxide are subjected to a reaction under normal temperature to generate indole-3-aromatic ketone, according to the novel synthetic method, the reaction mediums such as a transition-metal catalyst, an additive, acid and alkali are not required, the indole-3-aromatic ketone has good compatibility to a function group, the raw materials in the method have the advantages of simpleness and easy acquisition, and the method accords with a green chemistry scope.

Synthesis of indol-3-yl aryl ketones through visible-light-mediated carbonylation

A visible-light-catalyzed synthesis of indol-3-yl aryl ketones from aryldiazonium salts, CO and indoles at room temperature was developed. This process provides a useful method for the preparation of diverse indol-3-yl aryl ketones from readily accessible reactants under base-free, acid-free and transition-metal-free conditions.

Visible light-induced carbonylation of indoles with arylsulfonyl chlorides and CO

A novel and simple strategy for the visible light-induced efficient synthesis of indol-3-yl aryl ketones from readily available arylsulfonyl chlorides and indoles with CO at room temperature was developed. This metal-free protocol has good functional group tolerance and avoids the use of transition-metal catalysts, additives, and alkaline or acidic reaction medium.

Palladium-Catalyzed Carbonylation of Indoles using Aryl Formates as Bifunctional Reagents: A Route to Indol-3-yl Aryl Ketones

A new Pd-catalyzed carbonylation of indoles for the synthesis of indol-3-yl aryl ketones under CO-free conditions was developed. The reaction showed a broad substrate scope with moderate to excellent yields.

A novel and efficient Cu-promoted decarboxylative direct C3-acylation of N-substituted indoles with α-oxocarboxylic acids for the synthesis of 3-acylindoles was developed. The Royal Society of Chemistry.

Facile access to 3-acylindoles through palladium-catalyzed addition of indoles to nitriles: The one-pot synthesis of indenoindolones

A palladium-catalyzed addition of indoles to nitriles, leading to 3-acylindoles, was reported, and the scope of nitriles was investigated. The strategy described provides a more efficient and atom-economical alternative to indenoindolones. It was found that alkenyl, carbonyl, halogen, methoxy, and nitro groups on aryl nitriles, which could offer opportunities for further synthetic transformations, are all compatible with the conditions. N-unprotected indoles with electron-rich groups show excellent reactivity towards this addition reaction. Under the optimized conditions, an array of indenoindolones are obtained in synthetic useful yields from readily available indoles and nitriles in one pot. The results also show that both the electron-poor and electron-rich substituents could be introduced to indoles and nitriles and that the halogen atoms were compatible under the current conditions.
