Ruthenium-Catalyzed Oxidative Dearomatization of N-Boc Indoles

Ruthenium-catalyzed oxidative dearomatization ofN-Boc indoles for the synthesis of indolin-3-ones is described. TheN-Boc indoles can be transformed into indolin-3-ones in acetonitrile, using RuCl-(3)center dot 3H(2)O as catalyst and sodium periodate (1.5 equiv) as oxidant. Further, a possible mechanism has been proposed on the basis of control experiments.

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 1032350-13-2, in my other articles.

Quaternary stereocentres via catalytic enantioconvergent nucleophilic substitution reactions of tertiary alkyl halides

The development of efficient methods, particularly catalytic and enantioselective processes, for the construction of all-carbon quaternary stereocentres is an important (and difficult) challenge in organic synthesis due to the occurrence of this motif in a range of bioactive molecules. One conceptually straightforward and potentially versatile approach is the catalytic enantioconvergent substitution reaction of a readily available racemic tertiary alkyl electrophile by an organometallic nucleophile; however, examples of such processes are rare. Here we demonstrate that a nickel-based chiral catalyst achieves enantioconvergent couplings of a variety of tertiary electrophiles (cyclic and acyclic alpha-halocarbonyl compounds) with alkenylmetal nucleophiles to form quaternary stereocentres with good yield and enantioselectivity under mild conditions in the presence of a range of functional groups. These couplings, which probably proceed via a radical pathway, provide access to an array of useful families of organic compounds, including intermediates in the total synthesis of two natural products, (-)-eburnamonine and madindoline A.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 76-61-9, you can contact me at any time and look forward to more communication. Product Details of 76-61-9.

Annulation Cascades of N-Allyl-N-((2-bromoaryl)ethynyl)amides Involving C-H Functionalization

An annulation cascades of N-allyl-N-((2-bromoaryl)ethynyl)amides with terminal alkynes or 1,3-dicarbonyls involving C-H functionalization for producing 2,3-functionalized indoles has been first developed by means of Cu catalysis.

Aldehyde-derivatized indoles as fluorescent probes for hydration environments

Tryptophan derivatives have long been used as site-specific fluorescent probes. 4-cyanotryptophan emits in the visible region and is the smallest blue fluorescent amino acid probe. We performed UV-Vis, steady-state and time-resolved fluorescence spectroscopy on six aldehyde-derivatized indoles dissolved in water and found that indole-4-carboxaldehyde (I4A) has the largest redshifts among all reported indole derivatives and can emit in the green region of the visible spectrum, which suggests that substitution of the indole ring of Trp using I4A may make a green fluorescent amino acid probe. It differs from tryptophan by only 3 atoms and will be the smallest green fluorescent amino acid probe that has great potential to be used in spectroscopic and microscopic measurements of proteins. We also found that I4A could be used as a fluorescent probe to detect trace water in organic solvents since its maximum emission wavelength is extremely sensitive to local hydrogen-bonding status.

Synthesis of new hexahydro-5H-indolo[3,2-c]acridines and indolylbutanoic acids by Fischer cyclization of arylhydrazones

Arylhydrazones of 2,3,5,6,7,8-hexahydroacridin-4(1H)-ones and 7-amino-6-(arylhydrazono)-7-oxoheptanoic acids were cyclized by Fischer reaction, providing previously unknown polysubstituted indole derivatives. The starting hydrazones were synthesized under Japp-Klingemann reaction conditions by using 1,2,3,4,5,6,7,8-octahydroacridine-4-carboxamide and 2-oxocyclohexanecarboxamide as starting materials. It was established from the spectral data that the obtained 7-amino-6-(arylhydrazono)-7-oxoheptanoic acids existed as mixtures of (Z)- and (E)-isomers, but were converted to an individual (Z)- or (E)-isomer in DMSO solution.

Copper-Catalyzed Tandem O-Vinylation of Arylhydroxylamines/[3,3]-Rearrangement/Cyclization: Synthesis of Highly Substituted Indoles and Benzoindoles

Herein, we developed a copper-catalyzed O-vinylation of arylhydroxylamine using vinyliodonium salts as vinylation reagents to generate a transient O-vinyl-N-arylhydroxylamine that rapidly undergoes a [3,3]-sigmatropic rearrangement and subsequent cyclization/rearomatization to form a substituted indole.

Rhodium-Catalyzed Selective C-H Trideuteromethylation of Indole at C7 Position Using Acetic-d(6) Anhydride

Rhodium-catalyzed C7-selective decarbonylative trideuteromethylation of indoles with commercially available Ac2O-d(6) via C-H and C-C bond activation has been developed. The key to the high reactivity and regioselectivity of this transformation is the appropriate choice of an indole N-(PBu2)-Bu-t chelation-assisting group. This method has many advantages, including easy access and removal of the directing group, the use of cheap and widely available deuterium methylating source, no requirement of an external ligand or oxidant, a broader substrate scope, high efficiency, and the sole regioisomer.

Salt-tolerant plant growth-promoting Bacillus pumilus strain JPVS11 to enhance plant growth attributes of rice and improve soil health under salinity stress

Rice (Oryza sativa L.) growth and productivity has been negatively affected due to high soil salinity. However, some salt-tolerant plant growth-promoting bacteria (ST-PGPB) enhance crop growth and reduce the negative impacts of salt stress through regulation of some biochemical, physiological, and molecular features. Total thirty six ST-PGPB were isolated from sodic soil of eastern Uttar Pradesh, India, and screened for salt tolerance at different salt (NaCl) concentrations up to 2000 millimolar (mM). Out of thirty-six, thirteen strains indicated better growth and plant growth properties (PGPs) in NaCl amended medium. Among thirteen, one most effective Bacillus pumilus strain JPVS11 was molecularly characterized, which showed potential PGPs, such as indole-3acetic acid (IAA),1-aminocyclo propane-1-carboxylicacid (ACC) deaminase activity, P-solubilization, proline accumulation and exopolysaccharides (EPS) production at different concentrations of NaCl (0 -1200 mM). Pot experiment was conducted on rice (Variety CSR46) at different NaCl concentrations (0, 50, 100, 200, and 300 mM) with and without inoculation of Bacillus pumilus strain JPVS11. At elevated concentrations of NaCl, the adverse effects on chlorophyll content, carotenoids, antioxidant activity was recorded in non-inoculated (only NaCl) plants. However, inoculation of Bacillus pumilus strain JPVS11 showed positive adaption and improve growth performance of rice as compared to non-inoculated in similar conditions. A significant (P < 0.05) enhancement plant height (12.90-26.48%), root length (9.55-23.09%), chlorophyll content (10.13-27.24%), carotenoids (8.38-25.44%), plant fresh weight (12.33-25.59%), and dry weight (8.66-30.89%) were recorded from 50 to 300 mM NaCl concentration in inoculated plants as compared to non-inoculated. Moreover, the plants inoculated with Bacillus pumilus strain JPVS11showed improvement in antioxidant enzyme activities of catalase (15.14-32.91%) and superoxide dismutase (8.68-26.61%). Besides, the significant improvement in soil enzyme activities, such as alkaline phosphatase (18.37-53.51%), acid phosphatase (28.42-45.99%), urease (14.77-47.84%), and beta-glucosidase (25.21-56.12%) were recorded in inoculated pots as compared to non inoculated. These results suggest that Bacillus pumilus strain JPVS11 is a potential ST-PGPB for promoting plant growth attributes, soil enzyme activities, microbial counts, and mitigating the deleterious effects of salinity in rice.
