Hydroalkoxycarbonylation of olefins has been considered to be one of the most attractive methods to synthesize esters. Controlling the regioselectivities of linear esters (L) and branched esters (B) is a challenging project for researchers working in this reaction. Although most of the attention has been paid to control the regioselectivity through ligand design in homogeneous catalytic systems, study in the area is still limited. Herein, Ru-clusters/CeO2 is employed as a heterogeneous catalyst for the hydromethoxycarbonylation of styrene without any additives. After optimization of the reaction conditions, the conversion of styrene is > 99% with 83% and 12% regioselectivity of linear and branched ester, respectively. By using different supports (CeO2 (nanoparticle), CeO2-rod, and CeO2-cube), three catalysts including Ru-clusters/CeO2, Ru/CeO2-rod, and Ru/CeO2-cube are prepared and applied in the reaction. Structural characterizations demonstrate that the L/B ratio is related to the Ru size of supported Ru catalysts. Further Raman characterization and NH3-TPD demonstrate that the metal-support interaction and the concentration of oxygen vacancy of the catalyst have a great influence on the Ru size. The mechanism and kinetic analysis for this reaction are also investigated in this work. (C) 2020, Dalian Institute of Chemical Physics, Chinese Academy of Sciences. Published by Elsevier B.V.

Catalytic conversion of lignin to versatile aromatic compounds is attracting increasing attention. However, it is highly desirable but challenging to produce a specific chemical with high yield through lignin depolymerization in a one-pot process because of the complex structure of the lignin molecule (mainly composed of H, G, and S units). In this study, a series of metal-based deep eutectic solvents (M-DESs) were prepared and used for the catalytic tailoring of lignin H units to produce value-added methyl p-hydroxycinnamate (MPC). In particular, M-DES ChCl[FeCl3](2) showed excellent catalytic performance for the selective production of MPC as the sole product with high yield and selectivity (105.8 mg g(-1) and 74.1%, respectively). Extensive characterizations using 2D HSQC NMR, C-13 NMR, and GPC demonstrated that MPC was obtained from the selective tailoring of p-coumaric acid (pCA) units via the cleavage of ester bonds in lignin. Furthermore, M-DES ChCl[FeCl3](2) also exhibited efficiency to other herbaceous lignins, and showed excellent recyclability. Therefore, this work provides an effective strategy for the valorization of lignin.

Established electrodecarboxylative etherification protocols are based on Hofer-Moest-type reaction pathways. An oxidative decarboxylation gives rise to radicals, which are further oxidised to carbocations. This is possible only for benzylic or otherwise stabilised substrates. Here, we report the electrodecarboxylative radical-radical coupling of lithium alkylcarboxylates with 1-hydroxybenzotriazole at platinum electrodes in methanol/pyridine to afford alkyl benzotriazole ethers. The substrate scope of this electrochemical radical coupling extends to primary and secondary alkylcarboxylates. The benzotriazole products easily undergo reductive cleavage to the alcohols. They can also serve as synthetic hubs to access a wide variety of functional groups. This reaction prototype demonstrates that electrodecarboxylative C-O bond formation can be taken beyond the intrinsic substrate limitations of Hofer-Moest mechanisms.

Photoredox chemistry has greatly stimulated the application of radical based transformations in medicinal chemistry and early drug discovery in recent years. Carboxylate groups have been identified as traceless leaving groups that can be converted into radical intermediates capable of undergoing 1,4-conjugate addition reactions to Michael acceptors. Herein, we show the successful C-terminal derivatization of small peptide substrates by using this methodology in a parallel synthesis setting. Finally, we outline a general strategy for the gamma-homologation of several drugs derived from alpha-amino acids in a late stage functionalization (LSF) approach.

Background Several studies have reported the association between polymorphisms in Matrix metalloproteinases (MMPs) gene family and risk of Multiple sclerosis (MS). However, the results have been inconsistent and inconclusive. To resolve this issue, here we performed a systematic review and meta-analysis of the MMP-91562 C/T (rs3918242), MMP-3 (- 1612 5A/6A), and MMP-2 (- 1306 C/T) polymorphisms and susceptibility to MS. Methods We conducted a comprehensive systematic search in the major electronic database, including Scopus and PubMed to look up for relevant studies published before December 2019 that surveyed the association between the MMP-91562 C/T (rs3918242), MMP-3 (- 1612 5A/6A), and MMP-2 (- 1306 C/T) polymorphisms and susceptibility to MS. The level of association between the polymorphisms and susceptibility to MS in the polled analysis was determined by calculating the odds ratio (OR) and the corresponding 95% confidence interval (CI). Results We found 15 studies containing 2430 MS subjects and 2304 controls. A statistically significant association was observed in the all five comparisons of the MMP-91562 C/T polymorphism and MS risk as follows: dominant model (OR = 1.62, 95% CI = 1.03-2.53, P = 0.03), recessive model (OR = 2.69, 95% CI = 1.68-4.29, P < 0.001), allelic model (OR = 1.51, 95% CI = 1-2.28, P = 0.04), TT vs. CC model (OR = 3.20, 95% CI = 1.87-5.46, P < 0.001), and CT vs. CC model (OR = 1.53, 95% CI = 1.02-2.28, P = 0.04). Conclusions Our meta-analysis revealed significant association of MMP-9 (- 1562 C/T) Single-nucleotide polymorphism (SNP) with MS susceptibility that increased the disease risk.

The direct oxidation of alcohols to esters is an environmentally benign and cost-effective organic synthetic strategy, but it is still a great challenge to discover an economic, highly active, and long-term stable catalyst for efficient transformation of alcohols to esters under milder conditions. Herein, we developed cobalt and copper nanoparticle -co-decorated nitrogen-doped carbon catalysts (CoCu@NCn) through two steps of ball milling and calcination. It was found that CoCu@NCn could catalyze the oxidation of alcohols to esters effectively in the absence of basic additives. The catalytic activity was much higher than those of monometallic Co@NC2 and Cu@NC2 samples, and the catalyst can be conveniently recovered and quite steadily reused. Through a series of control experiments and characterizations, it is concluded that the remarkable catalytic performance of CoCu@NC2 was associated with the synergistic effect between the two metal components, the enhanced basic active sites and the active surface area.

Homogeneous chitosan/poly(methacrylic acid) solution containing Pd(2+)cations was successfully prepared by addition of pyridine-2-carboxaldehyde. Then, this homogeneous solution was smoothly electrospun into uniform composite nanofibers with mean diameter of 442 +/- 163 nm, followed by annealing at elevated temperature to improve the solvent resistance. Scanning electron microscopy (SEM) analysis shows that the solvent resistance of the composite nanofibers was improved with the increment of annealing temperature. FT-IR spectra demonstrate that the chemical structure of the composite nanofibers was not oxidized after annealing process. Moreover, the palladium species were homogeneously incorporated inside the composite nanofibers. The catalytic performance of these novel composite nanofibers was evaluated by Heck reaction. The catalysis result shows that these composite nanofibers were very efficient to catalyze the Heck reaction of aromatic iodides with acrylates with yields over 86%. Moreover, these composite nanofibers can be reused for 10 times with little decrement of yield.

In contrast to the plethora of large-bite-angle bisphosphine ligands available to transition-metal catalysis, the development of small-bite-angle bisphosphine ligands has suffered from the limited structural variations accessible on their single-atom-containing backbones. Herein, we report the design and applications of a discrete very small bite-angle bisphosphine ligand, namely, FMPhos. Featuring a fluorene-methylene unit appended on the single-carbon linker, the ligand harbors an unusually rigid backbone that presumably stabilizes its complexation with transition metals during catalysis. Compared with the known dppm ligand, it exhibited superior reactivity and regioselectivity in a number of alkene hydrofunctionalization reactions, catalyzed by iridium and rhodium.

Non-C-3-symmetric supramolecular helices are gaining interest for the design of hierarchical assemblies, for the compartmentalisation or the self-assembly of polymer chains and for application in asymmetric catalysis. Herein, N-substituted benzene-1-urea-3,5-biscarboxamide (BUBA) monomers, which consist of one urea and two carbon-connected amide functions linked to an aromatic ring, are introduced as an easily accessible class of C-2-symmetric supramolecular synthons. In apolar solvents, BUBA monomers assemble into long helical assemblies by means of hydrogen-bonding and aromatic interactions, as assessed by several analytical techniques. To probe the influence of the urea function, BUBA and related benzene-1,3,5-tricarboxamide (BTA) helical polymers have been compared, in terms of their thermodynamics of formation, stability, reversibility and chiral amplification properties. Similar to BTA, BUBA monomers form long helices reversibly through a highly cooperative mechanism and the helicity of their assemblies is governed by chiral amplification effects. However, precise quantification of their properties reveals that BUBA monomers assemble in a more cooperative manner. Also, chiral amplification operates to a higher extent in BUBA helices, as probed by both sergeants-and-soldiers and majority-rules experiments. Compatibility between urea and amide functions also allows the formation of co-assemblies that incorporate both BUBA and BTA monomers. Importantly, a small amount of chiral BUBA monomers in these co-assemblies is sufficient to obtain single-handed helices; thus paving the way towards the development of functional supramolecular helices.

Aims/Introduction Painful diabetic peripheral neuropathy (PDPN) has a significant impact on the patient’s quality of life. The prevalence of PDPN in the Middle East and North Africa region has been reported to be almost double that of populations in the UK. We sought to determine the prevalence of PDPN and its associated factors in type 2 diabetes mellitus patients attending secondary care in Qatar. Materials and Methods This was a cross-sectional study of 1,095 participants with type 2 diabetes mellitus attending Qatar’s two national diabetes centers. PDPN and impaired vibration perception on the pulp of the large toes were assessed using the Douleur Neuropathique en 4 questionnaire with a cut-off >= 4 and the neurothesiometer with a cut-off >= 15 V, respectively. Results The prevalence of PDPN was 34.5% (95% confidence interval [CI] 31.7-37.3), but 80% of these patients had not previously been diagnosed or treated for this condition. Arabs had a higher prevalence of PDPN compared with South Asians (P < 0.05). PDPN was associated with impaired vibration perception adjusted odds ratio (AOR) 4.42 (95% CI 2.92-6.70), smoking AOR 2.43 (95% CI 1.43-4.15), obesity AOR 1.74 (95% CI 1.13-2.66), being female AOR 1.65 (95% CI: 1.03-2.64) and duration of diabetes AOR 1.08 (95% CI 1.05-1.11). Age, poor glycemic control, hypertension, physical activity and proteinuria showed no association with PDPN. Conclusions PDPN occurs in one-third of type 2 diabetes mellitus patients attending secondary care in Qatar, but the majority have not been diagnosed. Arabs are at higher risk for PDPN. Impaired vibration perception, obesity and smoking are associated with PDPN in Qatar. Product Details of 103-26-4.
