Photoredox-Catalysis-Modulated, Nickel-Catalyzed Divergent Difunctionalization of Ethylene

Divergent synthesis that enables a catalytic reaction to selectively produce different products from common substrates will allow the charting of wider chemical space and the unveiling of distinct mechanistic paradigms. A common strategy for it employs different ligands to modulate organometallic catalysts. Dramatic developments in photocatalysis have enabled previously inaccessible transformations. In particular, photoredox catalysis modulates the oxidation state of transition-metal complexes, offering enormous opportunities for methodology development. Herein, we developed a photo-mediated divergent ethylene difunctionalization via modulating oxidation states of the nickel catalyst by using different photoredox catalysts. This work will inspire new perspectives for value-added chemical synthesis using ethylene as a feedstock and shed light on photoredox-catalyst-based divergent synthesis, which fundamentally differs from ligand-controlled transition-metal catalysis.Divergent synthesis represents a powerful strategy for directly accessing different molecular scaffolds originating from the same starting materials. Access to different end products via transition-metal catalysis is conventionally achieved by ligand control. We herein demonstrate the use of ethylene feedstock and commercially available aryl halides to accomplish the divergent synthesis of 1,2-diarylethanes, 1,4-diarylbutanes, or 2,3-diarylbutanes in a highly selective fashion through the synergistic combination of nickel and photoredox catalysis. Mechanistic studies suggest that the observed selectivity was due to different active states of Ni(I) and Ni(0) modulated by Ru- and Ir-based photoredox catalysts, respectively. The ability to access different organometallic oxidation states via photoredox catalysis promises to inspire new perspectives for synergistic transition-metal-catalyzed divergent synthesis.Functionalization of ethylene without polymerization is challenging under photo-irradiation conditions. We have demonstrated that the photo-transformation of ethylene can be controllable by merging photoredox and transition-metal catalysis. In our study, the use of different photoredox catalysts was able to modulate the oxidation state of the nickel catalyst. Through different oxidation states, the nickel-catalyzed couplings proceeded via distinct pathways to generate divergent ethylene difunctionalization products selectively from the same feedstock.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 4923-87-9

2-Phenylbenzo[b]thiophene-based antiestrogens with mammary tumor inhibiting activity

In this study we extended our studies on heterocyclic antiestrogens to 2-phenylbenzo[b]thiophenes which can be considered as isosteric to the 2- phenylindole system. We synthesized a number of 6-hydroxy-2-(4- hydroxyphenyl)benzo[b]thiophenes with carbamoyl and amino functions in the side chain at carbon-3 and analyzed their biological properties. The binding affinities for the estrogen receptor are mainly influenced by the chain length whereas the hormonal profile depends on the nature of the functional group. From this study 3-[10-(2,2,3,3,4,4,4,-heptafluorobutyl- methylcarbamoyl)decyl]-6-hydroxy-2-(4-hydroxyphenyl)benzo[b]thiophene (6e) emerged as an antiestrogen with all the characteristics of a pure antagonist. It did not stimulate gene expression in HeLa cells cotransfected with the expression vector for the human estrogen receptor HEGO and the luciferase reporter plasmid EREwtc luc nor did it show any estrogenic activity in the mouse uterus weight test. In the latter assay, it completely abrogated the stimulatory effect of estrone. Due to its antiestrogenic potency it strongly inhibited the growth of estrogen-sensitive human MCF-7 breast cancer cells with an IC50 value of 5 nM. These data suggest that an amide function is combination with the fluorination of the terminal carbon atoms is an appropriate modification to abolish the estrogenic action of the 2- phenylbenzothiophene system.

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.SDS of cas: 63675-74-1, you can also check out more blogs about63675-74-1

Synthesis and structure-activity relationships of second-generation hydroxamate botulinum neurotoxin A protease inhibitors

Botulinum neurotoxins are the most toxic proteins currently known. Based on a recently identified potent lead structure, 2,4-dichlorocinnamic acid hydroxamate, herein we report on the structure-activity relationship of a series of hydroxamate BoNT/A inhibitors. Among them, 2-bromo-4-chlorocinnamic acid hydroxamate, 2-methyl-4-chlorocinnamic acid hydroxamate, and 2-trifluoromethyl-4-chlorocinnamic acid hydroxamate displayed comparable inhibitory activity to that of the lead structure.

NaBH4-TMEDA and a palladium catalyst as efficient regio- and chemoselective system for the hydrodehalogenation of halogenated heterocycles

The pair NaBH4-TMEDA as hydride source and a palladium catalyst in THF prove to be an efficient system for the hydrodehalogenation of halogenated heterocycles with one or more heteroatoms. In general, Pd(OAc) 2-PPh3 rapidly hydrodehalogenates reactive halo-heterocycles such as bromo-pyridines, -quinolines, -thiophenes, -indoles, -imidazoles, etc., at room temperature in very good yields, whereas in most cases PdCl2(dppf) reduces less reactive halides such as chloro-pyridines, -quinolines, -pyrimidines and bromo-indoles, -benzofurans, etc. Moreover, PdCl2(tbpf) shows to be even more active removing the 2- and 5-chlorine from both thiophene and thiazole rings. The reaction conditions tolerate various functional groups, allowing highly chemoselective reactions in the presence of halide, ester, alkyne, alkene and nitrile substituents. Moreover, with a proper selection of the catalyst it is also possible to obtain a good control in the regioselective hydrodehalogenation of a variety of polyhalogenated substrates.

Diarylethene-modified nucleotides for switching optical properties in DNA

Diarylethenes were attached to the 5-position of 2′-deoxyuridine in order to yield three different photochromic nucleosides. All nucleosides were characterized with respect to their absorption and photochromic properties. Based on these results, the most promising photochromic DNA base modification was incorporated into representative oligonucleotides by using automated phosphoramidite chemistry. The switching of optical properties in DNA can be achieved selectively at 310 nm (forward) and 450 nm (backward); both wavelengths are outside the normal nucleic acid absorption range. Moreover, this nucleoside was proven to be photochemically stable and allows switching back and forth several times. These results open the way for the use of diarylethenes as photochromic compounds in DNA-based architectures.

Stereoselective Csp3?Csp2 Cross-Couplings of Chiral Secondary Alkylzinc Reagents with Alkenyl and Aryl Halides

We report palladium-catalyzed cross-coupling reactions of chiral secondary non-stabilized dialkylzinc reagents, prepared from readily available chiral secondary alkyl iodides, with alkenyl and aryl halides. This method provides alpha-chiral alkenes and arenes with very high retention of configuration (dr up to 98:2) and satisfactory overall yields (up to 76 % for 3 reaction steps). The configurational stability of these chiral non-stabilized dialkylzinc reagents was determined and exceeded several hours at 25 C. DFT calculations were performed to rationalize the stereoretention during the catalytic cycle. Furthermore, the cross-coupling reaction was applied in an efficient total synthesis of the sesquiterpenes (S)- and (R)-curcumene with control of the absolute stereochemistry.

Discovery of novel, potent, isosteviol-based antithrombotic agents

Thrombosis is a pathological coagulation process and can lead to many serious thrombotic diseases. Here, we report a novel potent antithrombotic compound (6k) based on isosteviol with anticoagulant and antiplatelet activities. 6k selectively inhibited FXa (Ki = 0.015 muM) against a panel of serine proteases and showed excellent anticoagulant activity (significant prolongation of ex vivo PT and aPTT over the vehicle, p < 0.01). 6k also significantly inhibited ADP-induced platelet aggregation in rats relative to the vehicle (p < 0.01). Furthermore, 6k exhibited potent ex vivo and in vivo antithrombotic activity in rats relative to the vehicle (p < 0.01 and p < 0.0001, respectively). Novel structure 6k, with potent antithrombotic activity, is expected to lead a promising approach for the development of antithrombotic agents.
