Formation of bis-benzimidazole and bis-benzoxazole through organocatalytic depolymerization of poly(ethylene terephthalate) and its mechanism

Environmental remediation through the recycling and upcycling of waste plastics is an urgent global concern. Accordingly, we herein demonstrate the organocatalyzed depolymerization of poly(ethylene terephthalate) (PET) with o-phenylenediamine (OPD) and 2-aminophenol (2AP) to form bis-benzimidazole and bis-benzoxazole, which can potentially be applied to the production of medicines, high-performance polymers, and organic electronics. Although high-temperature treatment at 190 degrees C was required, the neutral superbase 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) successfully facilitated two nucleophilic substitution reactions in one-pot, i.e., amidation or transesterification of PET followed by heterocycle formation to the amide or ester group. Theoretical studies with B3LYP density functional theory were performed for model reactions using methyl benzoate (MB) and OPD or 2AP. Consequently, we revealed that amidation favorably proceeds in the first depolymerization step and that the heterocycle formation predominantly results from nucleophilic attack to the amide intermediate by the anilinic NH2 or phenolic OH with the assistance of TBD. We also found that multiple hydrogen-bonding activations involving the bifunctional nature of TBD and the bidentate interactions of nucleophilic reagents such as OPD and 2AP with carbonyl oxygen atoms enable the one-pot formation of benzimidazoles and benzoxazoles from PET. Thus, this study not only demonstrates a new valuable method for upcycling of PET, but also offers a new synthetic route to benzimidazoles and benzoxazoles.

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. you can also check out more blogs about 148893-10-1. Product Details of 148893-10-1.

Synthesis, molecular modeling, and pharmacological evaluation of new 2-substituted benzoxazole derivatives as potent anti-inflammatory agents

In the present work, 2-substituted benzoxazole derivatives were synthesized from 2-(benzo[d]oxazol-2-yl) aniline. All the synthesized compounds were purified and characterized by H-1 NMR, C-13 NMR, and mass spectroscopy. All the compounds were pharmacologically evaluated for its in vitro anti-inflammatory efficacy using membrane stabilization and proteinase inhibitory methods. In addition to this, in silico molecular docking studies were carried out to predict the binding affinity of the synthesized benzoxazole derivatives with prostaglandin H2 synthase (PGHS) protein and trypsin enzyme. The results obtained from in vitro anti-inflammatory studies showed that compound 3, 4, and 6a showed good efficacy with percentage inhibition of 74.26 +/- 1.04, 80.16 +/- 0.24, and 70.24 +/- 0.68 for membrane stabilization activity 80.19 +/- 0.05, 85.30 +/- 1.04, and 75.68 +/- 1.28 towards proteinase inhibitory efficacy at a concentration of 100 mu g/mL which was on par to that of standards aceclofenac and etodolac. Molecular docking analysis showed that compounds 3 and 4 possess good binding affinity towards PGHS protein with a docking score of – 9.4 and – 9.3 kcal/mol respectively.

Synthesis and Anticancer Activity of Benzimidazole/Benzoxazole Substituted Triazolotriazines in Hepatocellular Carcinoma

Background: Receptor Tyrosine Kinases (RTK) are the main family of cell surface receptors for growth factors, hormones and cytokines which are responsible for cell growth and differentiation and are considered as an important therapeutic target in cancer. Objective: The aim of this study was to design, synthesise and conduct the biological evaluation of benzimidazole/benzoxazole substituted triazolotriazines as new anticancer agents. Methods: A series of benzimidazolyl and benzoxazolyl-linked triazolotriazines 8a-e and 9a-e were synthesized as receptor tyrosine kinase inhibitors. Target compounds were evaluated in HGF-induced cell proliferation assay in A549, MCF-7, HepG2 and MDA-MB-231 cancer cells. Results: Hepatocellular carcinoma was the most sensitive cell line towards the tested compounds and 8e was the most potent one on HepG2 cells with an IC50 value of 5.13 mu M which was close to crizotinib (HepG2 IC50 = 4.35 mu M) as a standard c-Met kinase inhibitor. c-Met kinase assay of 8e showed that this compound is not capable of inhibiting this enzyme and subsequently molecular docking confirmed the low affinity of 8e towards cMet active site and its possible anticancer mechanism through VEGFR-2 inhibition. Conclusion: Further in silico predictions revealed that 8e can be a drug candidate with favorable pharmacokinetic properties.

Synthesis of C-3-Symmetric star-shaped molecules containing 1,3-azoles via hetero-aryl Heck coupling

We have demonstrated a useful synthetic strategy to assemble star-shaped C-3-symmetric molecules containing 1,3-azole moieties at the periphery. To generate these C-3-symmetric heterocycles, we have employed the Pd/Cu-based coupling reactions. To this end, we have used benzoxazole, benzothiazole, and benzimidazole as coupling partners to generate the corresponding hetero-aryl Heck coupling products. (C) 2019 Published by Elsevier Ltd.

Effect of substitution on the solid-state fluorescence properties of styrylbenzoxazole derivatives with terminal dicyanomethylene group

Three styrylbenzoxazole derivatives with terminal dicyanomethylene group were studied in order to understand how minor modifications brought to the benzoxazole ring influence the photoluminescence (PL) properties. The three compounds, in which several molecular motions are allowed, were weakly fluorescent in organic solution. Remarkably, the unsubstituted (1) and methoxy (2) derivatives showed clear solid-state luminescence enhancement (SLE). Distinct emission characteristics were attributed to the formation of amorphous and crys-talline particles owing to scanning electron microscopy. These two compounds were also strongly luminescent as microcrystalline powders. Compound 1 that crystallized in herringbone configuration was a better emitter than the methoxy derivative 2, in which intermolecular interactions are more numerous, according to X-ray diffraction analysis. In contrast, compound 3 was virtually not emissive, confirming that in this series of dyes the presence of the hydroxy group is detrimental to PL emission, as rarely observed among SLE-active fluorophores.

Synthesis and properties of a novel highly thermal stable N-propargyl monomer containing benzoxazole ring

A novel highly thermal stable propargyl functional compound containing benzoxazole ring, N, N, N, N-tetra propargyl-5-amino-2-(p-aminophenyl) benzoxazole (TPAPB), was proposed and synthesized using a phase-transfer catalytic method. The cure behavior of TPAPB was investigated by non-isothermal differential scanning calorimetry analysis. The solubility and rheological properties of TPAPB, as well as its broad temperature window from 130 degrees C to 200 degrees C with low viscosity, offered excellent processability for TPAPB to be used as a potential monomer of thermosetting polymer resin. It was found that the glass transition temperature of cured TPAPB was 359 degrees C, and the temperature of 5% weight loss was 418 degrees C in argon with the char residue up to 70% at 700 degrees C. The polymerized resin exhibited high heat resistance and thermal stability, together with its processability, making it good candidate as highly heat-resistant polymer matrix for advanced composite applications.

Disubstituted Ferrocenyl Iodo- and Chalcogenoalkynes as Chiral Halogen and Chalcogen Bond Donors

Asymmetric catalysis based on halogen and chalcogen bonds (XB and ChB) is in its infancy, and the search for new chiral XB and ChB donors represents a crucial step toward its development. In this context, we designed and prepared new motifs containing three key substructures: namely, regions of electron charge density depletion centered on iodine and chalcogen atoms, the ethynyl functionality, and the planar chiral ferrocenyl platform. Nine ferrocenyl iodoalkynes were prepared as pure enantiomers by asymmetric synthesis. The XB donor property of racemic ferrocenyl iodoalkynes was demonstrated in solution in two benchmark reactions: the Ritter reaction and the benzoxazole synthesis from thioamides. In contrast, the ferrocenyl chalcogenoalkynes were far less active in these reactions. The potential of racemic and enantiopure ferrocenyl iodoalkynes as XB donors was also confirmed by X-ray diffraction analysis, showing I center dot center dot center dot C contacts between the electropositive u-hole of the iodine atom and electron-rich it clouds for all crystal structures studied in the solid state.
