Regioselective Palladium-Catalyzed C-H Bond Trifluoroethylation of Indoles: Exploration and Mechanistic Insight

A selective palladium-catalyzed trifluoroethylation reaction of indoles has been developed. The C-H bond activation process, using CF3CH2I as the fluoroalkyl source, can be employed to prepare a variety of 2-CF3CH2 substituted indoles. Moreover, because it displays a wide functional group tolerance, the process can be employed to synthesize CF3CH2-containing bioactive indoles through late-stage trifluoroethylation. The results of a preliminary mechanistic study and DFT calculations show that a beta-diketone, acting as an ionic palladium ligand, plays an important role in governing the efficiency of the palladium-catalyzed trifluoroethylation reaction by accelerating the oxidative addition step. In contrast, transfer of the indole N-H proton in the palladium center is involved in the rate-determining step.

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 613-84-3, in my other articles.

P-III-Chelation-Assisted Indole C7-Arylation, Olefination, Methylation, and Acylation with Carboxylic Acids/Anhydrides by Rhodium Catalysis

Rhodium-catalyzed C7-selective decarbonylative arylation, olefination, and methylation of indoles with carboxylic acids or anhydrides by C-H and C-C bond activation have been developed. Furthermore, C7-acylation products can also be generated selectively at a lower reaction temperature in the developed system. The key to the high reactivity and regioselectivity of this transformation is the appropriate choice of an indole N-PtBu2 chelation-assisted group. This method has many advantages, including easy access and removal of the directing group, the use of cheap and widely available coupling agents, no requirement of an external ligand or oxidant, a broad substrate scope, high efficiency, and the formation of a sole regioisomer.

A chemo- and regioselective C6-functionalization of 2,3-disubstituted indoles: highly efficient synthesis of diarylindol-6-ylmethanes

An organocatalytic chemo-and regioselective C6-functionalization of 2,3-disubstituted indoles has been established via a reaction with ortho-hydroxybenzyl alcohols, which afforded biologically important diarylindol- 6-ylmethanes in overall high yields (up to 99% yield). This protocol not only provides an efficient method for constructing biologically important diarylindol-6-ylmethane frameworks in an atom economical fashion, but also serves as a good example for the direct catalytic C6-functionalization of indoles, which have been rarely investigated. More importantly, the preliminary biological evaluation revealed that this new class of diarylindol-6-ylmethanes exhibited strong cytotoxicity to HeLa cell lines.

Death due to consumption of ibogaine: case report

Ibogaine is a psychotropic indole alkaloid extracted from the roots of the Tabernanthe iboga shrub from the Apocynaceae family. Depending on the taken dose, it can lead to stimulant effects, euphoria, visual and auditory hallucinations, along with auditory, olfactory, and gustatory synesthesia. In addition to its historical usage in spiritual rituals of African tribes, these days iboga extract presents a prohibited, alternative drug widely used as a part of addiction treatment. Ibogaine used in opioid withdrawal is associated with serious side effects and sudden deaths. Besides its main use as an anti-addiction medication in alternative medicine, in moderate doses (from 100mg to 1g) ibogaine most commonly causes a trance-like state. In this paper, we report the case of a heroin addict who died suddenly 5-12 hours after oral ingestion of powder labeled Tabernanthe iboga which had been bought online and used in the process of detoxification during an addiction treatment. The man was found dead in a rented apartment, where he was undergoing the addiction treatment. External examination revealed no lesions other than nonspecific injuries on the legs. The autopsy showed congestion of internal organs and pulmonary edema. Histopathological analysis of the heart showed neither macroscopic nor microscopic abnormalities. The concentration of ibogaine was 3.26mg/L. Moreover, systematic toxicological analyses of biological samples showed the presence of morphine and codeine. These data suggest that death, which occurred unnaturally after initiation of the treatment, was probably the result of the cardiovascular effects caused by the ibogaine powder. The presented case highlights the worldwide problem of various products being widely available over the internet and the danger associated with consumption thereof.

Environmentally benign, microwave-assisted chemoselective N-hydroxyalkylation of indoles with trifluoroacetaldehyde methyl hemiacetal

The chemoselective microwave-activated N-hydroxyalkylation of indoles using trifluoroacetaldehyde methylhemiacetal as the alkylating agent under mild conditions is described. The chemoselectivity of this reaction is determined by the solvent used. In dimethyl sulfoxide, the reaction occurs without the use of a strong base or a metal catalyst. This approach can be applied to a variety of different substituted indoles to obtain the corresponding N-alkylated products with high selectivity. The product 2,2,2-trifluoro-1-(1-H-indol-1yl)ethanols combine two moieties of frequent pharmacological interest: the indole core and a CF3-group containing a hydroxyalkyl substituent.

A robust heterogeneous Co-MOF catalyst in azide-alkyne cycloaddition and Friedel-Crafts reactions as well as hydrosilylation of alkynes

Organic reactions using metal-organic frameworks (MOFs) as catalysts are promising with regard to their environmentally friendly features and potential catalyst recyclability. A robust Co(ii)-MOF {[Co-2(l-mac)(4,4-bpt)(H2O)]center dot 3.5H(2)O}(n) (1) and its enantiomer {[Co-2(d-mac)(4,4-bpt)(H2O)]center dot 3.5H(2)O}(n) (2) (l/d-mac = basic forms of l/d-malic acid, 4,4-Hbpt = 3,5-di(pyridin-4-yl)-4H-1,2,4-triazole) have been gram-scale prepared under solvothermal conditions. Structural analysis reveals that mac manages Co(ii) ions to form 1-D chains, which are further extended via 4,4-bpt connectors into a noninterpenetrating 3D framework architecture. It was found that 1 can be as a heterogeneous catalyst for multiple organic reactions, such as azide-alkyne cycloaddition and Friedel-Crafts reactions with good isolated yields and good recycle runs (at least five times without substantial degradation). Additionally, 1 can promote hydrosilylation of alkynes under harsh conditions with moderate yield.

Behavioral Effects of Developmental Exposure to JWH-018 in Wild-Type and Disrupted in Schizophrenia 1 (disc1) Mutant Zebrafish

Synthetic cannabinoids can cause acute adverse psychological effects, but the potential impact when exposure happens before birth is unknown. Use of synthetic cannabinoids during pregnancy may affect fetal brain development, and such effects could be moderated by the genetic makeup of an individual. Disrupted in schizophrenia 1 (DISC1) is a gene with important roles in neurodevelopment that has been associated with psychiatric disorders in pedigree analyses. Using zebrafish as a model, we investigated (1) the behavioral impact of developmental exposure to 3 mu M 1-pentyl-3-(1-naphthoyl)-indole (JWH-018; a common psychoactive synthetic cannabinoid) and (2) whether disc1 moderates the effects of JWH-018. As altered anxiety responses are seen in several psychiatric disorders, we focused on zebrafish anxiety-like behavior. Zebrafish embryos were exposed to JWH-018 from one to six days post-fertilization. Anxiety-like behavior was assessed using forced light/dark and acoustic startle assays in larvae and novel tank diving in adults. Compared to controls, both acutely and developmentally exposed zebrafish larvae had impaired locomotion during the forced light/dark test, but anxiety levels and response to startle stimuli were unaltered. Adult zebrafish developmentally exposed to JWH-018 spent less time on the bottom of the tank, suggesting decreased anxiety. Loss-of-function in disc1 increased anxiety-like behavior in the tank diving assay but did not alter sensitivity to JWH-018. Results suggest developmental exposure to JWH-018 has a long-term behavioral impact in zebrafish, which is not moderated by disc1.
