Direct Access to Highly Functionalised Benzimidazoles and Benzoxazoles from a Common Precursor

Benzoxazole and benzimidazole are commonly encountered heterocycles in medicinal chemistry and their functionalisation around 1-, 2-, 5-, and/or 6-positions provides a wide range of molecules of biological interest. In this manuscript, a straightforward preparation of diversely and highly substituted benzimidazoles and benzoxazoles on these positions, from a common starting material, a 3,3-dibromoacrolein, is described. Such acrolein derivatives are almost never described in the literature or used as ‘building-block’ for organic synthesis. The double electrophilicity of this substrate was found to be advantageous for condensation with two equivalents of various 1,2-diaminobenzene or 2-aminophenol derivatives. This one-pot reaction performed under metal-free and mild conditions allows the creation of three new carbon-heteroatom bonds and affords the desired heterocycles.

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 392-56-3 is helpful to your research. Safety of Hexafluorobenzene.

One-Pot Multicomponent Reaction of Catechols, Ammonium Acetate, and Aldehydes for the Synthesis of Benzoxazole Derivatives Using the Fe(III)-Salen Complex

The Fe(III)-salen complex has been applied successfully as a catalyst for the novel, simple, efficient, and one-pot multicomponent synthesis of benzoxazole derivatives from catechols, ammonium acetate as the nitrogen source, and aldehydes (nontoxic and cheap alternatives of amines) for the first time. Using this procedure, a wide range of benzoxazoles was successfully synthesized in the presence of a catalyst in EtOH under mild conditions, and all products were obtained in excellent yields. To the best of our knowledge, this method is the first example of the multicomponent synthesis of benzoxazole derivatives using these starting materials. The notable features such as the use of air that is considered as a benign oxidant and EtOH as a green solvent, ease of product separation, readily available and inexpensive aldehydes, and mild conditions make our procedure more efficient and practical for organic synthesis. Moreover, the current protocol is successfully applied to synthesize desirable products on a large scale.

Fluorogenic 7-azidocoumarin and 3/4-azidophthalimide derivatives as indicators of reductase activity in microorganisms

A series of fluorogenic heterocyclic azides were prepared and assessed as reductase substrates across a selection of Gram-negative and Gram-positive microorganisms. The majority of these azides showed similar activity profiles to nitroreductase substrates. Microorganisms that do not produce hydrogen sulfide reduced the azides, indicating reductase activity was not linked to hydrogen sulfide production.

Rational design of novel benzisoxazole derivatives with acetylcholinesterase inhibitory and serotoninergic 5-HT4 receptors activities for the treatment of Alzheimer’s disease

A rigidification strategy was applied to the preclinical candidate donecopride, an acetylcholinesterase inhibitor possessing 5-HT4R agonist activity. Inspired by promising bioactive benzisoxazole compounds, we have conducted a pharmacomodulation study to generate a novel series of multitarget directed ligands. The chemical synthesis of the ligand was optimized and compounds were evaluated in vitro against each target and in cellulo. Structure-activity relationship was supported by docking analysis in human acetylcholinesterase binding site. Among the synthesized compounds, we have identified a novel hybrid 32a (3-[2-[1-(cyclohexylmethyl)-4-piperidyl]ethyl]-4-methoxy-1,2-benzoxazole) able to display nanomolar acetylcholinesterase inhibitory effects and nanomolar Ki for 5-HT4R.

Novel synthesis of high-molecular-weight prepolymer of poly(p-phenylene benzoxazole) in ionic liquids

Using ionic liquids (ILs) as the reaction solvent for the synthesis of prepolymer polyamide of poly(p-phenylene benzoxazole) (PBO) was investigated. The optimum condition of prepolymer preparation was determined in ILs. A series of 1,3-dialkylimidazolium ILs were used to be the reaction media of the polycondensation. The relationship between the molecular weight of prepolymer and the structure of ILs was analysed by changing the structure of the cation and species of anion of ILs. In order to prove the feasibility of the transformation, the prepolymer was used to prepare PBO in polyphosphoric acid media, and the conversion process was analyzed. The spinnability of the PBO solution was explored by the preparation of PBO fibers. The basic mechanical properties of PBO single fiber were tested. In a word, using 1,3-dialkylimidazolium ILs as the reaction solvents was feasible for the synthesis of high-molecular-weight PBO prepolymer, which could be a promising PBO preparation method.

Dye-doped starch microparticles as a novel fluorescent agent for the visualization of latent fingermarks on porous and non-porous substrates

Detection and visualization of latent fingermarks are research areas that have been extensively explored over the years, mainly in the search for new methods and to improve existing fingermark developers. The aim of the present study was to propose new fingermark developers in an attempt to improve existing methods, especially regarding characteristics such as sensitivity, selectivity and ease of visualization on various substrates. In addition, we looked for developers that are cheaper, more environmentally friendly and less harmful to the health of those who handle them often. For this, the formulation of the proposed fluorescent developers was based on starch, a natural and high abundant polymer matrix. The small amount of organic dye incorporated into this matrix considerably reduces any risk of inherent toxicity. The high photophysical stability of the novel developer due to the use of embedded dyes that exhibit the excited-state infra-molecular proton transfer (ESIPT) mechanism and a high Stokes shift confer important and relevant optical properties. The influence of fingermark age and sequential deposition were studied. The results of the present study show that these novel developers are efficient and promising, especially for detecting fresh and non-fresh fingermarks on porous and non-porous substrates. Furthermore, the high photophysical stability of these fluorescent microparticles allow for preserving developed prints for a long time without degradation (important for the chain of custody).

A novel series of 2-sulfonyl benzoxazoles containing 1,2,3-triazole nucleus was synthesized using highly efficient and environmentally benign microwave-assisted ionic liquids containing click synthesis. The newly synthesized compounds were screened for their anti-inflammatory and antibacterial activities. Among all the derivatives tested, compound 5c containing the 4-fluorophenyl group in the triazole ring exhibited the most potent anti-inflammatory activity and the remaining compounds have shown moderate to good activity compared to the reference drug. The antibacterial activity revealed that compound 5c has shown more potent activity than the standard drugs. [GRAPHICS]

Cyclometalated Iridium(III) Complexes Containing Benzoxazole Derivatives and Different Ancillary Ligands for Catalytic Oxidation of Toluene

The catalytic frequencies (TOF) are fairly high (up to 7.0 x 10(2) h(-1)) with excellent reliability, and the turnover number (TON) can reach 4.2 x 10(3) after 6 h of processing time.

Synthesis, molecular docking, and pharmacological evaluation of N-(2-(3,5-dimethoxyphenyl)benzoxazole-5-yl)benzamide derivatives as selective COX-2 inhibitors and anti-inflammatory agents

A series of N-(2-(3,5-dimethoxyphenyl)benzoxazole-5-yl)benzamide derivatives (3am) was synthesized and evaluated for their in vitro inhibitory activity against COX-1 and COX-2. The compounds with considerable in vitro activity (IC50<1M) were evaluated in vivo for their anti-inflammatory potential by the carrageenan-induced rat paw edema method. Out of 13 newly synthesized compounds, 3a, 3b, 3d, 3g, 3j, and 3k were found to be the most potent COX-2 inhibitors in the in vitro enzymatic assay, with IC50 values in the range of 0.06-0.71M. The in vivo anti-inflammatory activity of these six compounds (3a, 3b, 3d, 3g, 3j, and 3k) was assessed by the carrageenan-induced rat paw edema method. Compounds 3d (84.09%), 3g (79.54%), and 3a (70.45%) demonstrated significant anti-inflammatory activity compared to the standard drug ibuprofen (65.90%) and were also found to be safer than ibuprofen, by ulcerogenic studies. A docking study was done using the crystal structure of human COX-2, to understand the binding mechanism of these inhibitors to the active site of COX-2.
