Catalyst-free and additive-free reactions enabling C-C bond formation: a journey towards a sustainable future

This review focuses on the catalyst- and additive-free C-C bond forming reactions reported mostly from the year 2005 to date. C-C bond forming reactions are highly important as large and complex organic molecules can be derived from simpler ones via these reactions. On the other hand, catalyst- and additive-free reactions are economical, environmentally friendly and less sensitive to air/moisture, allow easy separation of products and are operationally simple. Hence, a large number of research articles have been published in this area. Though a few reviews are available on the catalyst-free organic reactions, most of them were published a few years ago. The current review excludes catalysts as well as additives and is specific to only C-C bond formation. Besides many organic name reactions, catalyst/additive-free C-H functionalizations, coupling reactions and UV-visible-light-promoted reactions are also discussed. Undoubtedly, the contents of this review will motivate readers to do more novel work in this area which will accelerate the journey towards a sustainable future.

Isolation and Identification of Extremophilic Bacteria with Potential as Plant Growth Promoters (Pgpb) of A Geothermal Site: A Case Study

‘Los Negritos is an extremophile geothermal site from Michoacan State, Mexico. Evidence of the diversity of its microbiota and its potential is still lacking. This study aimed to evaluate the bacterial communities by 16S metagenomics of the site and the potential of culturable bacteria isolated from the site by promoting growth plants (PGP) traits. Gemmatimonadetes phylum was the most abundant, followed by Actinobacteria, Alphaproteobacteria, and Firmicutes. A total of 15 culturable strains were isolated and identified. They belong to five different species: Bacillus seohaeanensis, Jeotgalibacillus alkaliphilus, Halobacillus andaensis, Thalassobacillus devorans, and Halobacillus campisalis. The phytohormone indole-3-acetic acid (IAA) production was in the interval from 14.78 to 46.52 mg L-1. The best IAA producers were T. devorans E18 and H. campisalis E20 with tryptophan and H. andaensis, T. devorans, and H. campisalis without tryptophan ranging 39.8 to 51.5 mg L-1. Phosphorous solubilization capability was detected in J. alkaliphilus and T. devorans, whereas B. seohaeanensis was the highest ammonium producer (34.1 +/- 0.52 mg L-1) and H. andaensis was positive for siderophore production. These results demonstrate that, despite the low diversity, bacteria isolated from ‘Los Negritos’ have the potential for plant growth promotion.

Green oxidation of indoles using halide catalysis

Oxidation of indoles is a fundamental organic transformation to deliver a variety of synthetically and pharmaceutically valuable nitrogen-containing compounds. Prior methods require the use of either organic oxidants (meta-chloroperoxybenzoic acid, N-bromosuccinimide, t-BuOCl) or stoichiometric toxic transition metals [Pb(OAc)(4), OsO4, CrO3], which produced oxidant-derived by-products that are harmful to human health, pollute the environment and entail immediate purification. A general catalysis protocol using safer oxidants (H2O2, oxone, O-2) is highly desirable. Herein, we report a unified, efficient halide catalysis for three oxidation reactions of indoles using oxone as the terminal oxidant, namely oxidative rearrangement of tetrahydro-beta-carbolines, indole oxidation to 2-oxindoles, and Witkop oxidation. This halide catalysis protocol represents a general, green oxidation method and is expected to be used widely due to several advantageous aspects including waste prevention, less hazardous chemical synthesis, and sustainable halide catalysis.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 2447-57-6, you can contact me at any time and look forward to more communication. Category: indole-building-block.

Distinguishing between Homogeneous and Heterogeneous Catalytic Activity in C-H Arylation of an Indole with Aryl Halides under Ligandless Conditions: Crucial Evidence from Real Catalytic Experiments

The kinetic approach for distinguishing between homogeneous and heterogeneous catalysis mechanisms by the analysis of differential selectivity was applied for direct C-H arylation of an indole with aryl halides under ligandless conditions. The differential selectivity of competing arylation of an indole with two aryl iodides or bromides and the differential regioselectivity of a parallel formation of C2- and C3-regioisomers of arylated indoles were studied by the simple method of phase trajectories needed for raw kinetic data only. The results obtained indicated that the selectivities strongly depended on the type (soluble or insoluble) and concentration of the Pd precursor. Considering the pathways of Pd transformations under the reaction conditions, this indicates a substantial contribution of catalysis occurring on the surface of metallic Pd (including nanoparticles).

Characterization of Indole-3-acetic Acid Biosynthesis and the Effects of This Phytohormone on the Proteome of the Plant-Associated Microbe Pantoea sp YR343

Indole-3-acetic acid (IAA) plays a central role in plant growth and development, and many plant-associated microbes produce IAA using tryptophan as the precursor. Using genomic analyses, we predicted that Pantoea sp. YR343, a microbe isolated from Populus deltoides, synthesizes IAA using the indole-3-pyruvate (IPA) pathway. To better understand IAA biosynthesis and the effects of IAA exposure on cell physiology, we characterized proteomes of Pantoea sp. YR343 grown in the presence of tryptophan or IAA. Exposure to IAA resulted in upregulation of proteins predicted to function in carbohydrate and amino acid transport and exopolysaccharide (EPS) biosynthesis. Metabolite profiles of wild-type cells showed the production of IPA, IAA, and tryptophol, consistent with an active IPA pathway. Finally, we constructed an Delta ipdC mutant that showed the elimination of tryptophol, consistent with a loss of IpdC activity, but was still able to produce IAA (20% of wild-type levels). Although we failed to detect intermediates from other known IAA biosynthetic pathways, this result suggests the possibility of an alternate pathway or the production of IAA by a nonenzymatic route in Pantoea sp. YR343. The Delta ipdC mutant was able to efficiently colonize poplar, suggesting that an active IPA pathway is not required for plant association.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 83-73-8. HPLC of Formula: C9H5I2NO.

Discovery of Novel Indole-Based Allosteric Highly Potent ATX Inhibitors with Great In Vivo Efficacy in a Mouse Lung Fibrosis Model

Autotaxin (ATX) is the dominant catalytic enzyme accounting for the lipid mediator lysophosphatidic acid (LPA) through hydrolysis of lysophosphatidylcholine (LPC). There is great interest in developing nonacidic ATX inhibitors with a specific binding mode to serve as potential in vivo effective therapeutic tools. Herein, dating from a high-throughput screening (HTS) product Indole-1 (740 nM), a dedicated optimization campaign was implemented through derivatizing the -COOH group to versatile linkers that well-bridged the indole skeleton and the hydrophobic pocket binding groups. Ultimately, it was established that the coexistence of a carbamate linker and -OH-group-containing amines could generally furnish excellent indole-based ATX inhibitors with even below 1 nM in vitro activities. Two optimal entities were advanced to a bleomycin-induced mice pulmonary fibrosis model, which exerted promising efficacy in alleviating the damaged lung texture caused by bleomycin exposure. The novel carbamate-containing indole-based ATX inhibitors with a concrete binding mode may contribute to the identification of potential therapeutic agents to intervene in fibrotic diseases.

N-Trifluoromethyl Hydrazines, Indoles and Their Derivatives

Reported herein is the first efficient strategy to synthesize a broad range of unsymmetrical N-CF3 hydrazines, which served as platform to unlock numerous currently inaccessible derivatives, such as tri- and tetra-substituted N-CF3 hydrazines, hydrazones, sulfonyl hydrazines, and valuable N-CF3 indoles. These compounds proved to be remarkably robust, being compatible with acids, bases, and a wide range of synthetic manipulations. The feasibility of RN(CF3)-NH2 to function as a directing group in C-H functionalization is also showcased.

Mild and Practical Indole C2 Allylation by Allylboration of in situ Generated 3-Chloroindolenines

C2 allylation of indole derivatives is a challenging but important transformation given the biological relevance of the products. Herein we report a selective C2 allylation strategy that proceeds via allylboration of in situ-generated 3-chloroindolenines. The reaction is mild, practical, and compatible with a wide range of C3-substituted indoles. As allylboronates are readily accessible from commercial precursors, various substituted allyl moieties can be introduced using the same protocol. To showcase the utility of this method we applied it to the synthesis of the natural product, tryprostatin B.

Application of 59-43-8, 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 59-43-8 is helpful to your research.
