And the article contained the following:

Herein, an electroreductive carboxylation of organic carbon-halogen bonds (X=Br and Cl) promoted by catalytic amounts of naphthalene as an organic mediator is reported. This transformation proceeds smoothly under mild conditions with a broad substrate scope of 59 examples, affording the valuable and versatile carboxylic acids in moderate to excellent yields without the need of costly transition metal, wasted stoichiometric metal reductants, or sacrificial anodes. Further late-stage carboxylations of natural product and drug derivatives demonstrate its synthetic utility. Mechanistic studies confirmed the activation of carbon-halogen bonds via single-electron transfer and the key role of naphthalene in this reaction. The experimental process involved the reaction of 4-(Bromomethyl)-1,1′-biphenyl(cas: 2567-29-5).Product Details of 2567-29-5

And the article contained the following:

In this study, authors designed and synthesized a series of N-sulfonamide-tetrahydroquinolines by mol. modeling and scaffold hopping strategy, aiming at improving the metabolic stabilities. Detailed SAR exploration led to identification of potent RORγt inverse agonists such as compound II with moderate binding affinity and inhibitory activity of Th17 cell differentiation. Binding mode of compound II with RORγt-LBD was revealed by mol. docking. Moreover, compound II showed lower intrinsic clearance in mouse liver microsomes compared with compound I and potent in-vivo efficacy and safety in psoriasis models, which can be used as a good starting point for the further optimization.

And the article contained the following:

Perfluoro-tert-butylation reaction has long remained a challenging task. We now report the use of 1,1-dibromo-2,2-bis(trifluoromethyl)ethylene (DBBF, I) as a practical reagent for perfluoro-tert-butylation reactions for the first time. Through a consecutive triple-fluorination process with DBBF and CsF, the (CF3)3C- species can be liberated and observed, which is able to serve as a robust nucleophilic perfluoro-tert-butylating agent for various electrophiles. The power of this synthetic protocol is evidenced by the efficient synthesis of structurally diverse perfluoro-tert-butylated mols. Multiple applications demonstrate the practicability of this method, as well as the superiority of perfluoro-tert-butylated compounds as sensitive probes. The perfluoro-tert-butylated product was successfully applied in 1H- and 19F-magnetic resonance imaging (MRI) experiment with an ultra-low field (ULF) MRI system. The experimental process involved the reaction of 4-(Bromomethyl)-1,1′-biphenyl(cas: 2567-29-5).Related Products of 2567-29-5

And the article contained the following:

The authors herein report the preparation of solid and salt-stabilized silylzinc pivalates from the corresponding silyllithium reagents via transmetalation with Zn(OPiv)2. These resulting organosilylzinc pivalates show enhanced air and moisture stability and unique reactivity in the silylative difunctionalization of alkenes. Thus, a practical chelation-assisted Ni-catalyzed regioselective alkyl and benzylsilylation of alkenes was developed, which provides an easy method to access alkyl silanes with broad substrate scope and wide functional group compatibility. Kinetic experiments highlight that the OPiv-coordination is crucial to improve the reactivity of silylzinc pivalates. Also, late-stage functionalizations of druglike mols. and versatile modifications of the products illustrate the synthetical utility of this protocol.

And the article contained the following:

The ring-opening difluoromethylation-halogenation of cyclic (thio)ethers is reported through a simple strategy relying on carbon-chalcogen bond activation with difluorocarbene. The reaction proceeds through in situ protonation of the previously little-known difluoromethylene oxonium or sulfonium ylide intermediate followed by ring-opening with halide ion to afford halogenated acyclic difluoromethyl (thio)ethers that can then be employed for further elaboration. TMSCF2X (X=Br, Cl) are unique reagents to achieve this synthetic purpose, which serve as both the difluorocarbene source and the halide ion source. The experimental process involved the reaction of 4-(Bromomethyl)-1,1′-biphenyl(cas: 2567-29-5).Related Products of 2567-29-5

And the article contained the following:

Seeking for new anticancer drugs with strong antiproliferative activity and simple mol. structure, we designed a novel series of compounds based on our previous reported pharmacophore model composed of five moieties. Antiproliferative assays on four tumoral cell lines and evaluation of human choline kinase CKα1 enzymic activity was performed for these compounds Among tested mols., those ones with biphenylmethyl groups showed better enzymic and antiproliferative activities. Docking and crystallization studies validate the hypothesis and confirm the results. The most active compound, the biphenylmethylquinolinium bromide I·Br-, induced significant arrest of the cell cycle in G0/G1 phase that ultimately lead to apoptosis, following the mitochondrial pathway, as demonstrated for other choline kinase inhibitors. However, addnl. assays reveal that the inhibition of choline uptake could also be involved in the antiproliferative activity of this class of compounds The experimental process involved the reaction of 4-(Bromomethyl)-1,1′-biphenyl(cas: 2567-29-5).Computed Properties of 2567-29-5
