Enantioselective Reaction between 2-(Cyanomethyl)azaarenes and N-Boc-amino Sulfones

A series of 2-(cyanomethyl)azaarenes containing benzothiazole or benzoxazole were designed and synthesized for asymmetric alpha-functionalization with N-Boc-amino sulfones. The Mannich adducts were obtained in high yields with good diastereo- and enantioselectivities. Aryl substituted amino sulfones were tolerated under the current conditions, and the reaction can be performed on gram scale in good results.

Design, synthesis and evaluation of anticancer activity of novel 2-thioxoimidazolidin-4-one derivatives bearing pyrazole, triazole and benzoxazole moieties

A novel series of substituted 2-thiohydantoin incorporated with benzoimidazole, pyrazole, triazole and/or benzoxazole moieties has been synthesized using (E)-3-[1-(4-bromophenyl) ethylideneamino]-2-thioxoimidazolidin-4-one 1 as the key starting material. The key material 1 also, reacted with an acetic anhydride, aromatic aldehydes, secondary amines, formaldehyde and triethyl orthoformate to give the corresponding acetyl, chalcone, Mannich bases and ethoxymethylene derivatives, respectively. The structures of the novel compounds were confirmed by spectral data and elemental analysis. The cytotoxic activity of all synthesized compounds was assessed in vitro against human hepatocellular cancer cell line (HePG-2) and breast carcinoma cell line (MCF-7). The bioassay results revealed that compound 14 has the best activity against HePG-2 cell line (IC50 = 2.33 mu g/mL), while compound 5 has the best activity against MCF-7 cell line (IC50 = 3.98 mu g/mL).

Mechanochemical Activation of Polymer-Embedded Photoluminescent Benzoxazole Moieties

Despite an increasing number of studies that have investigated mechanochemical effects in polymers, the number of polymers whose fluorescence characteristics change upon exposure to mechanical stress is still limited. We here report the investigation of a mechanofluorophore based on an aliphatic ester of 2-(2′-hydroxyphenyl)benzoxazole. The free benzoxazole displays green photoluminescence, which is associated with an excited state intramolecular proton transfer (ESIPT) process, whereas aliphatic esters of this compound emit blue light. When poly(methyl acrylate) containing an esterified benzoxazole mechanophore at the center of each chain molecule was exposed to ultrasound, a significant reduction of the molecular weight and pronounced changes of the photoluminescence emission and UV-vis absorption spectra were observed. The optical changes and the fact that the time-traces for molecular weight decrease and formation of the ESIPT capable species mirror each other indicate that the mechanophore is preferentially cleaved upon sonication and that such cleavage restores the 2-(2′-hydroxyphenyl)benzoxazole motif. The concept of mechanical activation of ester-protected ESIPT dyes, and more broadly of other hydroxyl group carrying fluorophores that change their emission properties upon ester formation and cleavage, should be general and allow access to a range of other mechanofluorophores.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 530-62-1, you can contact me at any time and look forward to more communication. SDS of cas: 530-62-1.

Syntheses, structures and properties of two mononuclear copper(I) complexes with N-heterocyclic ligands

Two mononuclear Cu(I) complexes, [Cu(PBO)(PPh3)(2)]?PF6?CH2Cl2 (1) and [Cu(PBM)(PPh3)(2)]?PF6 (2) (PBO = 2-(2?-pyridyl)benzoxazole, PBM = 2-(2?-pyridyl)benzimidazole, PPh3 = triphenylphosphine), have been synthesized and characterized by elemental analyses, IR, single crystal X-ray diffraction, fluorescence spectroscopy, and cyclic voltammetry. The structural analysis revealed that in 1 and 2, the Cu(I) ions are four-coordinate and the coordination geometry around the Cu(I) is distorted tetrahedral. Photoluminescent investigation shows that 1 and 2 exhibit distinct tunable green (523?nm)-to-yellow (557?nm) photoluminescence by varying the N-heterocyclic ligands. Electrochemical properties of 1 and 2 have been investigated by cyclic voltammetry. The results suggest the frontier molecular orbits and the HOMO-LUMO energy gaps of these cuprous complexes are effectively adjusted through the introduction of different N-heterocyclic ligands.

The photooxidative sensitization of bis(p-substituted diphenyl)iodonium salts in the radical polymerization of acrylates

The ability of two-component dyeing photoinitiating systems for the radical polymerization of 1,6-hexanediol diacrylate (HDDA) and 2-ethyl-2-(hydroxymethyl)-1,3-propanediol triacrylate (TMPTA) is presented. The systems under study comprised a hemicyanine dye as a sensitizer and iodonium salts that played a role of a coinitiator. The kinetic parameters of the polymerization reaction, such as the rate of polymerization (R-p) and the degree of conversion of monomer (C-%), were estimated. The thermodynamic feasibility of an electron transfer process in the systems studied was verified and calculated using the Rehm-Weller equation. It was found that a benzoxazole derivative in the presence of iodonium salts effectively initiated the polymerization of acrylate monomers. The polymerization rates of about 10(-7) s(-1) and the degree of conversion of acrylate groups from 20% to 50% were observed. The effects of photoinitiator structures on the initiating ability and spectroscopic properties of sensitizers are described in this article.

Unraveling the Effect on Luminescent Properties by Postsynthetic Covalent and Noncovalent Grafting of gfp Chromophore Analogues in Nanoscale MOF-808

Here, we demonstrate mimicking of photophysical properties of native green fluorescent protein (gfp) by immobilizing the gfp chromophore analogues in nanoscale MOF-808 and further exploring the bioimaging applications. The two virtually nonfluorescent gfp chromophore analogues carrying different functionalities, BDI-AE (COOH/COOMe) and BDI-EE (COOMe/COOMe) were immobilized in nanosized MOF-808 via postsynthetic modification. An H-1 NMR and IR study confirms that BDI-AE was coordinated in NMOF-808, whereas BDI-EE was just noncovalently encapsulated. Interestingly, the extremely weakly fluorescent monomers BDI-AE and BDI-EE (QY = 0.01-0.03%, lifetime = 0.01-0.03 ns) showed a 10(2)-fold increase in quantum efficiency with a significantly longer excited-state lifetime (QY = 1.8-5.6%, lifetime 0.89-1.49 ns) after immobilization in the NMOF-808 scaffold. Moreover, BDI-AE@MOF-808 has 4 times higher quantum efficiency as well as longer excited-state lifetime in comparison to BDI-EE@NMOF-808 due to the rigidity imposed in the chromophore upon coordination with Zr4+ in the former case. Further, a cell viability test performed for BDI-AE@NMOF-808 in HeLa cells confirmed the nontoxic nature of the material and, more importantly, bioimaging applications have also been explored successfully.

Efficient novel eutectic-mixture-mediated synthesis of benzoxazole-linked pyrrolidin-2-one heterocycles

In this study, new benzoxazole-linked pyrrolidinone heterocyclic compounds were synthesized by an eco-efficient strategy using substituted benzylamines and 2-aminophenol under ultrasonic irradiation in the presence of a newly designed metal-free deep eutectic solvent (DES). This DES was prepared by using a eutectic mixture of urea and a synthesized glycine-derived ionic liquid. X-ray diffraction and infrared spectroscopy were employed to investigate the structure of the ionic liquid and characterize the DES, respectively. This method exhibited key advantages of high productivity, a short reaction time, and simple processing. Moreover, this DES was easily separated from reaction mixtures and can be recycled for multiple reactions. (C) 2020 Elsevier B.V. All rights reserved.

Theoretical and experimental verification of molecular properties of novel benzamide derivatives using computational platforms and in vitro antibacterial activity

A series of N-(benzo[d]oxazol-2-ylcarbamothioyl)-2/4-substituted benzamides were synthesized by the reaction of 2-aminobenzoxazole with apposite benzoyl isothiocyanate. The structure of the newly synthesized compounds was confirmed by chemical tests, elemental (C, H, N, and S), and spectral (IR, H-1 NMR, C-13 NMR, and mass) analysis. All the synthesized compounds were evaluated experimentally for their antibacterial activity against Gram-positive and Gram-negative bacteria. The test results show moderate to potent antibacterial activity compared to the standard drug. The binding interactions of newly synthesized ligand and protein were correlated using a molecular docking study using a binding pocket of GlcN-6-P synthase. [GRAPHICS] .
