The chemistry of the carbon-transition metal double and triple bond: Annual survey covering the year 2018

This is a review of papers published in the year 2018 that focus on the synthesis, reactivity, or properties of compounds containing a carbon-transition metal double or triple bond. Highlights for the year 2018 include: (1) significant advances in the design of new precursors to carbene complex intermediates (e.g. alkynes, triazoles, and tosylhydrazones) that serve as safer alternatives to potentially hazardous diazo compounds, (2) continued vast employment of olefin metathesis for the synthesis of complex small molecules and polymers, including many examples of Z-selective and stereoretentive metathesis reactions, (3) development of biologically-inspired catalysts for carbene transfer reactions, (4) preparation of novel aromatic ring systems incorporating transition elements, (5) use of gold and platinum carbene-mediated transformations of alkynes in complex synthetic organic transformations, and (6) design of novel reaction pathways for capture of transition metal carbenoid intermediates.

Efficient transformation of electron-rich arenes into diethyl 3-arylisoxazole-4,5-dicarboxylates

Treatment of electron-rich arenes with Tf2O and DMF, followed by the reaction with NH2OH¡¤HCl and then with Oxone in the presence of diethyl acetylenedicarboxylate generated diethyl 3-arylisoxazole-4,5-dicarboxylates in good to moderate yields. Other alkynes could be also used for the present one-pot transformation of arenes into 3-arylisoxazole derivatives. Click here and insert your abstract text.

Effect of Building Block Transformation in Covalent Triazine-Based Frameworks for Enhanced CO2 Uptake and Metal-Free Heterogeneous Catalysis

Covalent triazine frameworks (CTFs) have provided a unique platform in functional material design for a wide range of applications. This work reports a series of new CTFs with two new heteroaromatic building blocks (pyrazole and isoxazole groups) through a building-block transformation approach aiming for carbon capture and storage (CCS) and metal-free catalysis. The CTFs were synthesized from their respective building blocks [(4,4?-(1H-pyrazole-3,5-diyl)dibenzonitrile (pyz) and 4,4?-(isoxazole-3,5-diyl)dibenzonitrile (isox))] under ionothermal conditions using ZnCl2. Both of the building blocks were designed by an organic transformation of an acetylacetone containing dinitrile linker to pyrazole and isoxazole groups, respectively. Due to this organic transformation, (i) linker aromatization, (ii) higher surface areas and nitrogen contents, (iii) higher aromaticity, and (iv) higher surface basicity was achieved. Due to these enhanced properties, CTFs were explored for CO2 uptake and metal-free heterogeneous catalysis. Among all, the isox-CTF, synthesized at 400 C, showed the highest CO2 uptake (4.92 mmol g?1 at 273 K and 2.98 mmol g?1 at 298 K at 1 bar). Remarkably, these CTFs showed excellent metal-free catalytic activity for the aerobic oxidation of benzylamine at mild reaction conditions. On studying the properties of the CTFs, it was observed that organic transformations and ligand aromatization of the materials are crucial factor to tune the important parameters that influence the CO2 uptake and the catalytic activity. Overall, this work highlights the substantial effect of designing new CTF materials by building-block organic transformations resulting in better properties for CCS applications and heterogeneous catalysis.

Catalytic efficiency of designed catalytic proteins

The de novo design of catalysts that mimic the affinity and specificity of natural enzymes remains one of the Holy Grails of chemistry. Despite decades of concerted effort we are still unable to design catalysts as efficient as enzymes. Here we critically evaluate approaches to (re)design of novel catalytic function in proteins using two test cases: Kemp elimination and ester hydrolysis. We show that the degree of success thus far has been modest when the rate enhancements seen for the designed proteins are compared with the rate enhancements by small molecule catalysts in solvents with properties similar to the active site. Nevertheless, there are reasons for optimism: the design methods are ever improving and the resulting catalyst can be efficiently improved using directed evolution.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 288-14-2, help many people in the next few years.288-14-2

New 1,2-diaryl-4-substituted-benzylidene-5-4H-imidazolone derivatives: Design, synthesis and biological evaluation as potential anti-inflammatory and analgesic agents

A new series of 1,2-diaryl-4-substituted-benzylidene-5-4H-imidazolone derivatives 10a-h was designed and synthesized for evaluation as selective COX-2 inhibitors, anti-inflammatory agents and as analgesic agents. All compounds were more selective for COX-2 isozyme and showed good in vivo anti-inflammatory activity. Compounds 10a, 10b, 10e and 10f were the most COX-2 selective compounds (S.I.?=?10.76, 10.87, 8.69 and 9.14 respectively), the most potent anti-inflammatory derivatives (ED50?=?65.7, 60.2, 76.3 and 107.4?mumol/kg respectively) in comparison with Celecoxib (COX-2 S.I.?=?8.61, ED50?=?82.2?mumol/kg) and were less ulcerogenic (ulcer indexes?=?1.22?3.02) than Ibuprofen (ulcer index?=?20.25) and comparable to Celecoxib (ulcer index?=?2.93). The four derivatives (10a, 10b, 10e and 10f) showed considerable analgesic activities which are clearly parallel to their anti-inflammatory activities.

Catalysis in medicinal chemistry

The advent of transition-metal catalysis (and likewise, bio-catalysis, photoredox-catalysis and organo-catalysis, etc.) promises to greatly increase access to diverse chemical matter in medicinal chemistry, but new catalytic reactions often fail to deliver product in applied synthesis. In order to deliver on the promise of catalysis, we need to learn how to use it to prepare the types of molecules that are relevant in biological systems. The dimensionality of trying to understand the rules for what causes catalysis to fail on diverse new substrates is a daunting problem that requires systematic, simplified thought. This perspective suggests an organized course of action to enable the generation of data to understand how to turn on catalysis for efficient synthesis of diverse molecules in medicinal chemistry.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 201150-73-4!, 288-14-2

Bifunctional Hydrogen Bonding of Imidazole with Water Explored by Rotational Spectroscopy and DFT Calculations

Laser vaporization of imidazole in the presence of an argon buffer gas has allowed the generation and isolation of two isomers of an imidazole monohydrate complex, denoted herein as imidH2O and H2Oimid, within a gas sample undergoing supersonic expansion. Imidazole and water are respectively proton-Accepting and proton-donating in imidH2O, but these roles are reversed in the H2Oimid complex. Both isomers have been characterized by chirped-pulse Fourier transform microwave spectroscopy between 7.0 and 18.5 GHz. The ground-state rotational spectra of four isotopologues of imidH2O and three isotopologues of H2Oimid have been measured. All spectra have been assigned and fitted to determine rotational (A0, B0, C0), centrifugal distortion (DJ, DJK), and nuclear quadrupole coupling constants (chiaa(N1), [chibb(N1)-chicc(N1)], chiaa(N3), and [chibb(N3)-chicc(N3)]). Structural parameters (r0 and rs) have been accurately determined from measured rotational constants for each isomer. The imidH2O complex contains a nonlinear hydrogen bond ((O-HbN3) = 172.1(26) in the experimentally determined, r0 geometry) between the pyridinic nitrogen of imidazole and a hydrogen atom of H2O. The DFT calculations find that the H2Oimid complex also contains a nonlinear hydrogen bond between the oxygen atom of water and the hydrogen attached to the pyrrolic nitrogen of imidazole ((OH1-N1) = 174.7). Two states observed in the spectrum of H2Oimid, assigned as 0- and 0+ states, confirm that large amplitude motions occur on the time scale of the molecular rotation. Density functional theory has been performed to characterize these large amplitude motions.
