Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 54288-70-9, molcular formula is C5H11Br2N, introducing its new discovery. Recommanded Product: 54288-70-9

A sensitive amine-responsive disassembly of self-assembled AuI-CuI double salts was observed and its utilization for the synergistic catalysis was enlightened. Investigation of the disassembly of [Au(NHC)2][CuI2] revealed the contribution of Cu-assisted ligand exchange of N-heterocyclic carbene (NHC) by amine in [Au(NHC)2]+ and the capacity of [CuI2]? on the oxidative step. By integrating the implicative information coded in the responsive behavior and inherent catalytic functions of d10 metal complexes, a catalyst for the oxidative carbonylation of amines was developed. The advantages of this method were clearly reflected on mild reaction conditions and the significantly expanded scope (51 examples); both primary and steric secondary amines can be employed as substrates. The cooperative reactivity from Au and Cu centers, as an indispensable prerequisite for the excellent catalytic performance, was validated in the synthesis of (un)symmetric ureas and carbamates.

Synthetic Route of 54288-70-9, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.54288-70-9, Name is 4-Bromopiperidine hydrobromide, molecular formula is C5H11Br2N. In a Article，once mentioned of 54288-70-9

A copper-catalyzed reductive cross-coupling reaction of nonactivated alkyl tosylates and mesylates with alkyl and aryl bromides was developed. It provides a practical method for efficient and cost-effective construction of aryl-alkyl and alkyl-alkyl C=C bonds with stereocontrol from readily available substrates. When used in an intramolecular fashion, the reaction enables convenient access to various substituted carbo- or heterocycles, such as 2,3-dihydrobenzofuran and benzochromene derivatives.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 54288-70-9, name is 4-Bromopiperidine hydrobromide, introducing its new discovery. Application In Synthesis of 4-Bromopiperidine hydrobromide

A simple and efficient iron-catalyzed protodehalogenation of alkyl and aryl halides using phenylhydrosilane is disclosed. The reaction utilizes FeCl3 without the requirement of ligands. Unactivated alkyl and aryl halides were successfully reduced in good yields; sterically hindered tertiary halides were also reduced including the less reactive chlorides. The scalability of this methodology was demonstrated by a gram-scale synthesis with a catalyst loading as low as 0.5 mol%. Notably, disproportionation of phenylsilane leads to diphenylsilane that further reduces the halides. Preliminary mechanistic studies revealed a non-radical pathway and the source of hydrogen is PhSiH3via deuterium labeling studies. Our methodology represents simplicity and provides a good alternative to typical tin, aluminum and boron hydride reagents.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 54288-70-9 is helpful to your research. Application In Synthesis of 4-Bromopiperidine hydrobromide

4-Hydroxy-1,2,3-triazole moiety as bioisostere of the carboxylic acid function: a novel scaffold to probe the orthosteric gamma-aminobutyric acid receptor binding site

The correct application of bio(iso)steric replacement, a potent tool for the design of optimized compounds, requires the continuous development of new isosters able to respond to specific target requirements. Among carboxylic acid isosters, as the hydroxylated pentatomic heterocyclic systems, the hydroxy-1,2,3-triazole represents one of the most versatile but less investigated. With the purpose to enlarge its bioisosteric application, we report the results of a study devoted to obtain potential biomimetics of the gamma-aminobutyric acid (GABA), the major inhibitory neurotransmitter in the central nervous system (CNS). A series of N1- and N2- functionalized 4-hydroxy-1,2,3-triazole analogues of the previous reported GABAAR ligands, including muscimol, 4-PIOL, and 4-PHP has been synthesized and characterized pharmacologically. Furthermore, this study led to development of straightforward chemical strategies directed to decorate the hydroxytriazole core scaffold, opening for further elaborative studies based on this system. The unsubstituted N1- and N2-piperidin-4-yl-4-hydroxy-1,2,3-triazole analogues (3a, 4a) of 4-PIOL and 4-PHP showed weak affinity (high to medium micromolar range), whereas substituting the 5-position of the triazole core with a 2-naphthylmethyl or 3,3-diphenylpropyl led to binding affinities in the low micromolar range. Based on electrostatic analysis and docking studies using a alpha1beta2gamma2 GABAAR homology model we were able to rationalize the observed divergence in SAR for the series of N1- and N2- piperidin-4-yl-4-hydroxy-1,2,3-triazole analogues, offering more detailed insight into the orthosteric GABAAR binding site.

Reductive sp3-sp2 Coupling Reactions Enable Late-Stage Modification of Pharmaceuticals

Late-stage derivatization of pharmaceutically relevant scaffolds relies on the availability of highly functional-group tolerant reactions. Reactions that increase the sp3 character of molecules enable the pursuit of more selective and well-tolerated pharmaceuticals. Herein, we report the use of sp3-sp2 cross-electrophile reductive couplings to modify a generic ATP-competitive kinase inhibitor with a broad range of primary and secondary alkyl halide coupling partners.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.54288-70-9,4-Bromopiperidine hydrobromide,as a common compound, the synthetic route is as follows.

54288-70-9, To a solution of 4-bromopiperidine hydrobromide (3.0 g, 12.2 mmol) in tetrahydrofuran (30 ml) were added 1-{[(benzyloxy)carbonyl]oxy}-2,5-pyrrolidinedione (3.20 g, 12.9 mmol), N-methylmorpholine (1.62 ml, 14.7 mmol) and 4-N,N-dimethylaminopyridine (30 mg) at room temperature, and stirred at room temperature for 16 hours. The reaction solution was poured into water and extracted with ethyl acetate. The organic layer was washed with a 1N-aqueous hydrochloric acid solution, dried over anhydrous magnesium sulfate and distilled under reduced pressure to remove the solvent, and the resulting residue was purified by a silica gel column chromatography (eluent: hexane/ethyl acetate = 1/1) to obtain benzyl 4-bromo-1-piperidinecarboxylate (3.58 g, 98percent).

The synthetic route of 54288-70-9 has been constantly updated, and we look forward to future research findings.
