Bronsted Acid-Catalyzed Cyclopropanation of Indoles Using alpha-Aryl-alpha-diazoacetates

Metal-free cyclopropanation of N-protected indoles with alpha-aryl-alpha-diazoacetates proceeded by using a catalytic amount of triflic imide as a Bronsted acid catalyst. The use of a catalytic amount of methyl phenylacetate improved the efficiency of the Bronsted acid-catalyzed cyclopropanation. A reaction mechanism including C-protonation of diazoacetates with HNTf2, followed by formal [3+2] cycloaddition with indoles and 1,3-rearrangement was proposed for the cyclopropanation.

Chiral Bronsted Acid from Chiral Phosphoric Acid Boron Complex and Water: Asymmetric Reduction of Indoles

A new chiral Bronsted acid, generated in situ from a chiral phosphoric acid boron (CPAB) complex and water, was successfully applied to asymmetric indole reduction. This designer acid catalyst, which is more acidic than TsOH as suggested by DFT calculations, allows the unprecedented direct asymmetric reduction of C2-aryl-substituted N-unprotected indoles and features good to excellent enantioselectivities with broad functional group tolerance. DFT calculations and mechanistic experiments indicates that this reaction undergoes C3-protonation and hydride-transfer processes. Besides, bulky C2-alkyl-substituted N-unprotected indoles are also suitable for this system.

Application of 107-43-7, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 107-43-7 is helpful to your research.

Synthesis of Functionalized Spirocyclic Indolines by Visible Light-Induced One-Pot Sequential Difluoromethylative Dearomatization, Hydroxylation, and Substitution Reactions

Herein we describe an one-pot protocol for visible light-induced synthesis of functionalized spirocyclic indolines under mild conditions by means of a process involving sequential difluoromethylative dearomatization, hydroxylation, and substitution reactions of indole derivatives. The transformation proceeds via a hydroxylated acetal pool intermediate that can react with various nucleophiles. Several of the phosphine-oxide and indole-substituted products showed good fungicidal activity, suggesting that this protocol might be useful in the agrochemical field.

Modification of Bischler-Mohlau indole derivatives through palladium catalyzed Suzuki reaction as effective cholinesterase inhibitors, their kinetic and molecular docking studies

Due to the immense importance of aryl indole nucleus, herein we report the palladium-catalyzed arylation of N-substituted 2-aryl indole utilizing Suzuki-Miyaura cross coupling methodology. The biological screening for cholinesterase inhibition of the resulted biaryl indole moieties was carried out to evaluate their pharmacological potential, expecting to involve the development of new therapeutics for various inflammatory, cardiovascular, gastrointestinal and neurological diseases. This research work also involved the use of utilization of microwave-assisted organic synthesis (MAOS) for the synthesis of Bischler-Mohlau indole which is further biarylated via palladium-catalyzed cross coupling reaction. All the synthetic compounds (3a-n) were tested for cholinesterase inhibition and exhibited high level of AChE inhibitory activities. Interestingly, compounds 3m and 3n were found to be dual inhibitors, however, remaining compound exhibited no inhibitory activity against BChE. The biological potential of the resulted compounds was explained on the basis of molecular docking studies, performed against AChE and BChE, exploring the probable binding modes of most potent inhibitors.

Enantioselective Copper(II)/Box-catalyzed Synthesis of Chiral beta(3)-Tryptophan Derivatives

beta-Amino acids and their derivatives are important building blocks for the preparation of various bioactive compounds and materials. We developed a highly efficient method for the synthesis of beta(3)-tryptophan derivatives based on enantioselective Friedel-Crafts alkylation of indoles with phthaloyl-protected aminomethylenemalonate in the presence of chiral Cu(OTf)(2)/iPrBox complex as a catalyst. A wide range of indoles with electron-donating and electron-withdrawing substituents gave the desired products in high yields (up to 99 %) and excellent enantioselectivities (up to 99 % ee). In the case of pyrrole the Friedel-Crafts product was obtained in up to 90 % yield and up to 82 % ee.

Divergent Functionalization of N-Alkyl-2-alkenylanilines: Efficient Synthesis of Substituted Indoles and Quinolines

An efficient divergent functionalization of N-alkylated ortho-alkenylanilines to substituted indoles and quinolines has been accomplished by employing rhodium-catalyzed cross-dehydrogenative coupling and silver-mediated oxidative cyclization, respectively. The developed methods tolerate various functional groups and allow the synthesis of substituted indoles and quinolines in good to excellent yield. Synthetic utility is demonstrated through conversion to an indole with antimicrobial activity and C-H bond functionalization of 2-arylquinolines. Furthermore, a plausible mechanism was proposed based on preliminary mechanistic investigations.

Micropropagation through indirect organogenesis in Solanum capsicoides All., and assessment of clonal fidelity using ISSR markers

Solanum capsicoides All., is an important medicinal plant which is used as a source of ‘Kantakari’ (medicine for phlegm disorders) in India. The restricted distribution of the plant in Kerala along with its overexploitation necessitates the development of a protocol for in vitro propagation of S. capsicoides. The present study reports the effects of four different cytokinins (2 isopentenyl adenine (2iP), benzyl adenine (BAP), kinetin (KIN), and zeatin (ZEA)) in combination with indole 3-butyric acid (IBA) on indirect organogenesis of S. capsicoides from in vitro grown seedling explants such as cotyledon, shoot tip, and hypocotyl. Maximum shoot development was observed from cotyledon explants inoculated on MS medium supplemented with 2.46 mu M IBA and 4.56 mu M ZEA. An average of 17 +/- 0.5 shoots per cotyledon with an average length of 0.53 +/- 0.03 cm was observed. After subculture, an average of 20 +/- 1 shoots was observed in cotyledon explants inoculated on Murashige and Skoog medium supplemented with 2.46 mu M IBA and 6.84 mu M ZEA. Clonal fidelity of regenerated plants was confirmed using DNA based molecular marker, intersimple sequence repeat (ISSR). Clonal fidelity test revealed 0% polymorphism and the PIC value 0 which indicate no diversity from seed-borne plants. The protocol thus developed can be used for rapid multiplication and conservation of S. capsicoides.

An efficient and selective procedure was developed for the direct C2-H arylation of indoles using a Pd-loaded metal-organic framework (MOF) as a heterogeneous catalyst and the nontoxic biomass-derived solvent gamma-valerolactone (GVL) as a reaction medium. The developed method allows for excellent yields and C-2 selectivity to be achieved and tolerates various substituents on the indole scaffold.
