Palladium-Catalyzed Dual C(sp(2))-H Functionalization of Indole-2-carboxamides Involving a 1,2-Acyl Migration: A Synthesis of Indolo[3,2-c]quinolinones

A novel Pd/Cu catalytic system to construct indolo[3,2-c]quinolinones has been developed starting from indole-2-carboxamides, Substrates were transformed into indolo[3,2-c]quinolinones through dual C(sp(2))-H functionalization of the indole moiety and arene, in which a carbonyl 1,2-migration was involved. The corresponding products were obtained in moderate to excellent yields with a wide substrate scope.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 624-49-7, in my other articles.

Stereoselective Alkylation of Indole with 5-Arylidene-Meldrum’s Acids in the Presence of Organocatalysts

Background: Indole motif is frequently present in biologically active compounds. Enantiomerically pure or enriched 2,2-dimethyl-5-(aryl(1H-indol-3-yl)methyl)-1,3 -dioxane-4,6-diones can be considered as a convenient starting point for the synthesis of a indole ring fused with cyclic ketones with biological activity. Preparation of chiral 2,2-dimethyl-5-(aryl(1H-indol-3-yl)methyl)-1,3-dioxane-4,6-diones requires the reaction of indole with 2,2-dimethyl-5-arylidene-1,3-dioxane-4,6-diones in the presence of chiral catalysts or other source of chiral induction. Methods: Enantioselective Friedel-Crafts alkylation of indole has been performed with 2,2-dimethyl-5-arylidene-1,3-dioxane-4,6-diones in the presence of organocatalysts to give 5-((1H-indol-3yl)(aryl)methyl)-2,2-dimethyl-1,3-dioxane-4,6-diones. Broad scope of organocatalysts as well as various temperatures and solvents used for the reaction were tested. Results: 2,2-Dimethyl-5-(aryl(1H-indol-3-yl)methyl)-1,3-dioxane-4,6-diones were obtained with quantitative yield and enantiomeric ratio 1:3 using thiourea organocatalyst. Also a new spectroscopic method for discrimination of 5-((1H-indol-3-yl)(aryl)methyl)-2,2-dimethyl-1,3-dioxane-4,6-diones enantiomers was developed. Conclusion: Enantioselective Friedel-Crafts alkylation of indole has been developed. In the presence of thiourea catalysts, 2,2-dimethyl-5-arylidene-1,3-dioxane-4,6-diones react with indole to give 2,2-dimethyl-5-(aryl(1H-indol-3-yl)methyl)-1,3 -dioxane-4,6-diones with good yields and reasonable ee.

Acylative Coupling of Amine and Indole Using Chloroform as a Carbonyl Group

Chloroform-mediated acylative coupling of amines with indoles has been developed.

Ruthenium- catalyzed synthesis of indole derivatives from N- aryl-2-aminopyridines and alpha- carbonyl sulfoxonium ylides

Indole is a ubiquitous structural motif with important applications in many areas of chemistry. Given this, a simple and efficient Ru(ii)-catalyzed synthesis of indole via intermolecular annulation of N-aryl-2-aminopyridines and sulfoxonium ylides was proposed and accomplished. Excellent selectivity and good functional group tolerance of this transformation were observed. This protocol provides easy access to a wide variety of useful indoles in the presence of a commercially available [Ru(p-cymene)Cl-2](2) catalyst. A possible mechanism for the reaction pathway was also proposed. More importantly, this reaction will offer a useful method for the construction of enantioenriched indole frameworks.

Asymmetric Dearomatization of Indole Derivatives with N-Hydroxycarbamates Enabled by Photoredox Catalysis

Dearomatization of indoles provides efficient synthetic routes for substituted indolines. In most cases, indoles serve as nucleophiles. Reported here is an asymmetric dearomatization reaction of indole derivatives that function as electrophiles. The combination of a photocatalyst and chiral phosphoric acid open to air unlocks the umpolung reactivity of indoles, enabling their dearomatization with N-hydroxycarbamates as nucleophiles. A variety of fused indolines bearing intriguing oxy-amines were constructed in excellent yields with moderate to high enantioselectivities. Mechanistic studies show that the realization of two sequential single-electron transfer oxidations of the indole derivatives is key, generating the configurationally biased carbocation species while providing the source of stereochemical induction. These results not only provide an efficient synthesis of enantioenriched indoline derivatives, but also offer a novel strategy for further designing asymmetric dearomatization reactions.

A new class of C-N axial chirality based on N-indole sulfonamides has been disclosed. This new axially chiral N-indole sulfonamides were constructed by NaClO-promoted couplings of 3-substituted indoles with chiral amino acid-based sulfonamides. A series of structurally diverse N-indole sulfonamide-based atropisomers were prepared using this established method. The stability of these structurally interesting atropisomers highly relied on the C3-substituents of indoles and side chains of amino acid derivatives.
