The double functionalization of styrenes through Cu-mediated assisted tandem catalysis was developed. The reaction was initiated by Cu-catalyzed aziridination and the subsequent nucleophilic ring-opening, which was triggered by the addition of (NH4)(2)S2O8 as an oxidant of Cu-catalyst to form a variety of C-C and C-X bonds. The expansion to three contiguous catalytic cycles led to the synthesis of functionalized indolines by one-pot operation.

Polymer functionality greatly determines many of the key properties of these materials, such as glass-transition temperature, electrical and thermal conductivity, thermal stability, mechanical strength, and processability. Despite the importance of polymer functionality in determining material properties, the synthesis of functional polymers, with well-defined molecular weights and compositions, can still present a significant challenge, with many of the methods related to pre- or postpolymerization modification lacking synthetic scope, or requiring harsh functionalization conditions or transition-metal coupling reactions to install the desired functionality. Perfluoroaromatic systems are promising for the preparation of novel polymer architectures given that they can be readily functionalized using simple nucleophilic chemistries under very mild basic conditions. While promising, these systems have displayed some drawbacks. Previous work has shown that perfluoroaromatics, such as perfluoropyridine, can demonstrate a high degree of chemical reversibility with heteroatom nucleophiles. If the synthetic potential of these systems is to be realized, then a strategy for the rational design of stable monomers must be developed. Herein, we report the design, synthesis, and characterization of a series of unexplored heteroatom-based ring-opening metathesis polymerization (ROMP)-active monomers containing a reactive perfluoropyridine pendent group, which can be used to readily prepare a wide variety of aryl ether-functionalized polymers, using both pre- and postpolymerization modification strategies. We also establish a direct connection between the dihedral angle of the monomer and its propensity to undergo reversible addition reactions, establishing functional criteria for the design of pre- and postmodifiable systems.

Formula: C8H8O2. I found the field of Chemistry very interesting. Saw the article Application of bis(phosphinite) pincer nickel complexes to the catalytic hydrosilylation of aldehydes published in 2021, Reprint Addresses Zhang, J; Chen, XNA (corresponding author), Henan Normal Univ, Sch Chem & Chem Engn, Henan Key Lab Boron Chem & Adv Energy Mat, Xinxiang 453007, Henan, Peoples R China.; Chen, XNA (corresponding author), Zhengzhou Univ, Coll Chem & Mol Engn, Zhengzhou 450001, Peoples R China.. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde.

A series of bis(phosphinite) (POCOP) pincer ligated nickel complexes, [2,6-(tBu(2)PO)(2)C6H3]NiX (X = SH, 1; SCH2Ph, 2; SPh, 3; NCS, 4; N-3, 5), were used to catalyse the hydrosilylation of aldehydes. It was found that both complexes 1 and 2 are active in catalysing the hydrosilylation of aldehydes with phenylsilane and complex 1 is comparatively more active. The expected alcohols were isolated in good to excellent yields after basic hydrolysis of the resultant hydrosilylation products. However, no reaction was observed when complex 3 or 4 or 5 was used as the catalyst. The results are consistent with complexes 1 and 2 serving as catalyst precursors, which generate the corresponding nickel hydride complex [2,6-(tBu(2)PO)(2)C6H3]NiH in situ, and the nickel hydride complex is the active species that catalyses this hydrosilylation process. The in situ generation of the nickel hydride species was supported by both experimental results and DFT calculation.

With the increasing incidence of antibiotic resistance, new antibacterial agents having novel mechanisms of action hence are in an urgent need to combat infectious diseases caused by multidrug-resistant (MDR) pathogens. Four novel series of substituted 9-arylalkyl-10-methylacridinium derivatives as FtsZ inhibitors were designed, synthesized and evaluated for their antibacterial activities against various Gram-positive and Gram-negative bacteria. The results demonstrated that they exhibited broad-spectrum activities with substantial efficacy against MRSA and VRE, which were superior or comparable to the berberine, sanguinarine, linezolid, ciprofloxacin and vancomycin. In particular, the most promising compound 15f showed rapid bactericidal properties, which avoid the emergence of drug resistance. However, 15f showed no inhibitory effect on Gram-negative bacteria but biofilm formation study gave possible answers. Further target identification and mechanistic studies revealed that 15f functioned as an effective FtsZ inhibitor to alter the dynamics of FtsZ self-polymerization, which resulted in termination of the cell division and caused cell death. Further cytotoxicity and animal studies demonstrated that 15f not only displayed efficacy in a murine model of bacteremia in vivo, but also no significant hemolysis to mammalian cells. Overall, this compound with novel skeleton could serve as an antibacterial lead of FtsZ inhibitor for further evaluation of drug-likeness. (C) 2021 Elsevier Masson SAS. All rights reserved.

Possible application of incorporating a well-known drug (benzocaine) with cyanoacetamide function to get a powerful synthon ethyl 4-cyanoacetamido benzoate. This synthetic intermediate was used as a precursor for the synthesis of triazine, pyridone, thiazolidinone, thiazole and thiophene scaffolds containing the benzocaine core. Facile coupling, Michael addition, condensation and nucleophilic attack reactions were used to synthesize our targets. The structural features of the synthesized scaffolds were characterized using IR,H-1 NMR,C-13 NMR and mass spectroscopy. The antibacterial activities against Gram-positive (Staphylococcus aureus,Bacillus subtilis) and Gram-negative bacteria (Escherichia coli,Pseudomonas aeruginosa) were evaluated using ampicillin as a reference drug. DNA/methyl-green colorimetric assay of the DNA-binding compounds was also performed. Theoretical studies of the newly synthesized compounds based on molecular docking and QSAR study were conducted. The molecular docking studies were screened by MOE software for the more potent antibacterial agent28band each native ligand against four ofS. aureusproteins 1jij, 2xct, 2w9s and 3t07. [GRAPHICS] .

Atkamine is a complex marine pyrroloiminoquinone alkaloid that comprises a heptacyclic scaffold bearing five different heterocycles and four contiguous stereocenters, and therefore it is a highly challenging target for synthetic chemists. We herein reported a modular synthetic strategy toward this alkaloid, featuring a formal [5 + 2] annulation and an asymmetric Michael addition. The efficient synthesis of the long-chain aliphatic aldehyde and chiral amino acetal fragments have been achieved. A simplified tetracyclic intermediate bearing the core structure of atkamine has been successfully constructed through the formal [5 + 2] annulation.

Based on our previously reported Bcl-2/Mcl-1 dual inhibitor 4-thiomorpholinyl-2-cyano-3-amidinophenalenone (A1) that simultaneously occupies the p2 and p4 hydrophobic pockets of Bcl-2 and Mcl-1, we optimized molecules with different bond angles of the groups extending to the p4 pocket and bulky hydrophobic groups to explore p2. Research on structure-activity relationship resulted in a new derivative B4 that is capable of occupying both the p2 and p4 more deeply and completely than A1, with K-i values determined by fluorescence polarization assay (FPAs) improving to 0.31 mu M for Bcl-2 and 0.16 mu M for Mcl-1. Furthermore, B4 exhibited selective lethality on cancer cells over normal cells. It showed stronger apoptosis induction than (-)-gossypol on a Bcl-2/Mcl-1-dependent cancer cell line and killed an Mcl-1-dependent cell line which is resistant to ABT-199 treatment.

Modular beta-borylacrylates have been validated as programmable, ambiphilic C-3-synthons in the cascade annulation of 2-halo-phenol derivatives to generate structurally and electronically diverse coumarins. Key to this [3+3] disconnection is the BPin unit which serves a dual purpose as both a traceless linker for C(sp(2))-C(sp(2)) coupling, and as a chromophore extension to enable inversion of the alkene geometry via selective energy transfer catalysis. Mild isomerisation is a pre-condition to access 3-substituted coumarins and provides a handle for divergence. The method is showcased in the synthesis of representative natural products that contain this venerable chemotype. Facile entry into pi-expanded estrone derivatives modified at the A-ring is disclosed to demonstrate the potential of the method in bioassay development or in drug repurposing.
