Regioselective Functionalization of Enamides at the alpha-Carbon via Unsymmetrical 2-Amidoallyl Cations

A new method to functionalize enamides via an intermediacy of unsymmetrical 2-amidoallyl cations is reported. Generated under mild Br¡ãnsted acid catalysis, these reactive species were found to undergo addition with various nucleophiles at the less substituted alpha-carbon to produce highly substituted enamides in high yields with complete control of regioselectivity.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 16136-52-0, help many people in the next few years.Application In Synthesis of 4-Cyanoindole

PIII-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.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 4837-90-5, and how the biochemistry of the body works.Application of 4837-90-5

Manganese-catalyzed synthesis of monofluoroalkenes: Via C-H activation and C-F cleavage

The manganese-catalyzed alpha-fluoroalkenylation of arenes via C-H activation and C-F cleavage has been described. This protocol provides a very useful method for the synthesis of monofluoroalkenes with predominant unconventional E-isomer selectivity which complements the existing strategies for the access to these molecular architectures. In addition, the selectivity of beta-defluorination in the catalytic cycle not only determines the configurations of the products but also obviates the use of external oxidants, providing a good example in the exploitation of manganese-catalyzed redox-neutral C-H transformations.

Bis(nitroxide) methanofullerene as SOD-mimetic in reactions with catecholamines

The reactions of a SOD-mimetic, bis(nitroxide) methanofullerene, with dopamine and 6-hydroxydopamine and the properties of its adsorption and Langmuir mono- and transferred layers were studied by methods of UV spectroscopy and EPR. The used fullerene derivative oxidizes catecholamines to cyclic and noncyclic quinones, whereas in a medium of phytic acid their oxidation products can be reduced. The inhibition effect of nitroxide fullerene in a phytic acid medium on the autocatalytic process of dopamine oxidation to its neurotoxic metabolite can be used for both the biomimetic prediction of stability of catecholamines and therapy of neurodegenerative diseases.

Micro-structured polydopamine films via pulsed electrochemical deposition

Polydopamine (PDA) films are interesting as smart functional materials, and their controlled structured formation plays a significant role in a wide range of applications ranging from cell adhesion to sensing and catalysis. A pulsed deposition technique is reported for micro-structuring polydopamine films using scanning electrochemical microscopy (SECM) in direct mode. Thereby, precise and reproducible film thicknesses of the deposited spots could be achieved ranging from 5.9 +/? 0.48 nm (1 pulse cycle) to 75.4 nm +/? 2.5 nm for 90 pulse cycles. The obtained morphology is different in comparison to films deposited via cyclic voltammetry or films formed by autooxidation showing a cracked blister-like structure for high pulse cycle numbers. The obtained polydopamine spots were investigated in respect to their electrochemical properties using SECM approach curves. Quantitative kinetic data in dependence of the film thickness, the substrate potential, and the used redox species were obtained.

Intramolecular reactions of alkynes with furans and electron rich arenes catalyzed by PtCl2: The role of platinum carbenes as intermediates

5-(2-Furyl)-1-alkynes react, with PtCl2 as catalyst, to give phenols. On the basis of DFT calculations, a cyclopropyl platinacarbene complex was found as the key intermediate in the process. The cyclopropane and dihydrofuran rings of this intermediate open to form a carbonyl compound, which reacts with the platinum carbene to form an oxepin, which is in equilibrium with an arene oxide. When the reaction is carried out in the presence of water, dicarbonyl compounds are obtained, which support the proposed mechanism. Other cyclizations of alkynes with furans or electron-rich arenes give products of apparent Friedel-Crafts-type reactions, although these processes could also proceed by pathways involving the formation of cyclopropyl platinum carbenes.

Toxic effects of brominated indoles and phenols on zebrafish embryos

Organobromine compounds in the marine environment have been the focus of growing attention in past years. In contrast to anthropogenic brominated flame retardants, other brominated compounds are produced naturally, e.g., by common polychaete worms and algae. Brominated phenols and indoles assumed to be of biogenic origin have been detected in water and sediment extracts from the German Bight. These substances as well as some of their isomers have been tested with the zebrafish embryo test and were found to cause lethal as well as nonlethal malformations. The zebrafish test was able to detect a log K OW-related toxicity for bromophenols, suggesting nonpolar narcosis as a major mode of action. Different effect patterns could be observed for brominated indoles and bromophenols. The comparison of effective concentrations in the zebrafish embryo test with the concentrations determined in water samples suggests the possibility that brominated indoles may affect early life stages of marine fish species in the North Sea.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. category: indole-building-block, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 52415-29-9, in my other articles.
