Modern Annulation Strategies for the Synthesis of Cyclo[ b ]fused Indoles

2,3-Annulated indoles exhibit a broad spectrum of biological activities. Various annulation strategies are applied to generate these scaffolds from prefunctionalized aniline or indole derivatives. Only a few methodologies allow the direct annulation of indole itself, often associated with regioselectivity issues or restrictions on available substitution patterns. More recently, ruthenium-catalyzed cascade transformations of readily available propargyl alcohols have been applied to the selective synthesis of various cyclo[ b ]fused indoles directly from indole. These efficient processes provide rapid access to intricate molecular structures from simple starting materials and facilitate the preparation of drug-like molecules.

Computational study of Ru-catalyzed cycloisomerization of 2-alkynylanilides

The reaction mechanism of Ru-catalyzed cycloisomerization of 2-alkynylanilides to 3-substituted indole or 2-substituted indole was analyzed at the B3LYP level of density functional theory. The solvation effect of the system was also considered by SMD model. The calculation results show that the reaction system first forms a ruthenium pi-alkyne complex. On the one hand, the cyclization reaction of the amino group and the alkyne carbon in the reaction precursor complex directly forms the 2-substituted indole product. On the other hand, the benzene ring in the reaction complex undergoes 1,2-carbon migration on the CaeC triple bond to form the vinylidene complex. After cyclization and hydrogen transfer, the catalyst is regenerated to obtain 3-substituted indole product. The latter reaction process has relatively lower activation free energy and is also the main reaction channel for this reaction, which is consistent with published experimental results. This study provides a reasonable reaction mechanism and effective experimental supplement.

A concise and regioselective synthesis of 6-bromo-5-methoxy-1H-indole-3-carboxylic acid and its derivatives: Strategic development toward core moiety of Herdmanine D

A concise, regioselective and highly efficient strategy for the construction of 6-bromo-5-methoxy-1H-indole-3-carboxylic acid has been developed through trifluoroacetylated indole driven hydrolysis. The developed protocol has the advantage of selectively directing bromine substituent on one position. The formation of this regioselective product was confirmed by (HNMR)-H-1 data. The attractive feature of this new strategy is that the 6-bromo-5-methoxy-1H-indole-3-carboxylic acid is an important scaffold of anti-inflammatory naturally occurring compound Herdmanine D. Furthermore, bromo indoles bearing carboxylic acid group were further functionalized in amide derivatives by using various aromatic/aliphatic amines through ultrasonic irradiation.

Electrochemically enabled functionalization of indoles or anilines for the synthesis of hexafluoroisopropoxy indole and aniline derivatives

An environmentally benign electrochemically enabled site-selective functionalization of indole or aniline derivatives with hexafluoroisopropanol in the presence of tetrabutyl ammonium hexafluorophosphate as the redox catalyst and electrolyte was demonstrated in this work. Under mild electro-oxidation conditions, a series of hexafluoroisopropoxy indole and aniline derivatives with pharmacological activity were obtained. This conversion does not need transition metals and oxidants, and has good functional group tolerance. The in vitro cytotoxicity of all compounds was evaluated by the MTT assay against four human cancer cell lines. The results revealed that hexafluoroisopropoxy indoles have good antitumor activity and compound 2i increased the intracellular levels of ROS and inhibited apoptosis in HeLa cells.

Tea leaves biochar as a carrier of Bacillus cereus improves the soil function and crop productivity

The application of biochar for plant growth and yield is of great importance. A combination of biochar and potent plant growth-promoting rhizobacteria (PGPR) may contribute extensively to crop production. The present investigation revealed the role of phosphate solubilizing bacteria and different biochars produced from tea leaves (Camellia sinensis L.). Biochar was prepared at 350 degrees C (B1) and 600 degrees C (B2) temperatures by using the pyrolysis tank. Seven bacterial strains were isolated from various types of soil collected from Mansehra, Pakistan. On the basis of phosphate solubilization and indole acetic acid production, one strain (Bacillus cereus) was applied with biochar. A greenhouse experiment was carried out to evaluate biochar as carriers for inoculant on mung bean (Vigna mungo) plant by comparing it with peat moss. Plastic pots of 15 x 18 cm(2) were filled with 1:3 of sand and autoclaved garden soil. Results revealed that biochar produced at a higher temperature (B2) showed greater shelf life as compared to peat. Among bacterial inoculation of Bacillus cereus with biochar at 600 degrees C improved soil properties i.e., soil organic carbon (14%), dissolved organic carbon (17%), total nitrogen (39%), Olsen phosphorus (36%) with enhanced microbial biomass (C-mic (17%), N-mic (36%), and P-mic (56%)), enzyme activity (urease (12%), dehydrogenase (40%), and phosphatase (49%)), crop growth and N-2-fixation (54%) over control (peat). Additionally, high-temperature biochar inoculated with Bacillus cereus (B2 + BC) significantly (P <= .05) enhanced the Proteobacteria (11%), Firmicutes (46%), Actinobacteria (20%), and Cyanobacteria (33%) community as compared to peat alone. It is concluded that biochar formulated at high temperature and its co-inoculation with bacteria (Bacillus cereus) may enhance soil fertility, growth, and yield of mung bean.

Sulfinate and Carbene Co-catalyzed Rauhut-Currier Reaction for Enantioselective Access to Azepino[1,2-a]indoles

A carbene and sulfinate co-catalyzed intermolecular Rauhut-Currier reaction between enals and nitrovinyl indoles is disclosed. The carbene catalyst activates the enal and the sulfinate co-catalyst activates the nitrovinyl indole. Both activation processes are realized via the formation of covalent bonds between the catalysts and substrates to generate catalyst-bound intermediates. The dual catalytic reaction affords azepino[1,2-a]indole products with excellent stereoselectivity. Our study demonstrates the unique involvement of sulfinate as an effective nucleophilic catalyst in activating electron-deficient alkenes for asymmetric reactions. This dual catalytic approach should also encourage future explorations of both sulfinate and carbene catalysts for new reactions.

Detosylative (Deutero)alkylation of Indoles and Phenols with (Deutero)alkoxides

An efficient strategy for N/O-(deutero)alkylation of indoles and phenols with alkoxides/alcohols as the alkylation reagents is described. The consecutive detosylation/alkylation transformations feature mild reaction conditions, high ipso-selectivity, and good functional group tolerance (>50 examples). A one-pot selective N-alkylation of unprotected indoles with alcohols and TsCl is also realized. The application of this method is demonstrated by the introduction of isotope-labeled (CD3 and (CH3)-C-13) groups using the readily accessible labeled alcohols and the synthesis of pharmaceuticals.

Arylation of indoles using cyclohexanones dually-catalyzed by niobic acid and palladium-on-carbons

3-Arylindoles were easily constructed from indoles and cyclohexanone derivatives using a combination of catalytic niobic acid-on-carbon (Nb2O5/C) and palladium-on-carbon (Pd/C) under heating conditions without any oxidants. The Lewis acidic Nb2O5/C promoted the nucleophilic addition of indoles to the cyclohexanones, and the subsequent dehydration and Pd/C-catalyzed dehydrogenation produced the 3-arylindoles. The additive 2,3-dimethyl-1,3-butadiene worked as a hydrogen acceptor to facilitate the dehydrogenation step.
