Metal-free approach for hindered amide-bond formation with hypervalent iodine(III) reagents: application to hindered peptide synthesis

A new bio-inspired approach is reported for amide and peptide synthesis using a-amino esters that possess a potential activating group (PAG) at the ester residue. To activate the ester functionality under mild metal-free conditions, we exploited the facile dearomatization of phenols with hypervalent iodine(III) reagents. Using a pyridine hydrogen fluoride complex, highly reactive acyl fluoride intermediates can be successfully generated, thereby allowing for the smooth formation of sterically hindered amides and peptides from bulky amines and a-amino esters, respectively.

Real-Time Fluctuations in Single-Molecule Rotaxane Experiments Reveal an Intermediate Weak Binding State during Shuttling

We report on the use of atomic force microscopy (AFM) to identify and characterize an intermediate state in macrocycle shuttling in a hydrogen bonded amide-based molecular shuttle. The [2]rotaxane consists of a benzylic amide macrocycle mechanically locked onto a thread that bears both fumaramide and succinic amide-ester sites, each of which can bind to the macrocycle through up to four intercomponent hydrogen bonds. Using AFM-based single-molecule force spectroscopy, we mechanically triggered the translocation of the ring between the two principal binding sites (stations) on the axle. Equilibrium fluctuations reveal another interacting site involving the two oxygen atoms in the middle of the thread. We characterized the ring occupancy distribution over time, which confirms the intermediate in both shuttling directions. The study provides evidence of weak hydrogen bonds that are difficult to detect using other methods and shows how the composition of the thread can significantly influence the shuttling dynamics by slowing down the ring motion between the principal binding sites. More generally, the study illustrates the utility that single-molecule experiments, such as force spectroscopy, can offer for elucidating the structure and dynamics of synthetic molecular machines.

The Potential Benefits of Palmitoylethanolamide in Palliation: A Qualitative Systematic Review

Palmitoylethanolamide (PEA) is a nutraceutical endocannabinoid that was retrospectively discovered in egg yolks. Feeding poor children with known streptococcal infections prevented rheumatic fever. Subsequently, it was found to alter the course of influenza. Unfortunately, there is little known about its pharmacokinetics. Palmitoylethanolamide targets nonclassical cannabinoid receptors rather than CB1 and CB2 receptors. Palmitoylethanolamide will only indirectly activate classical cannabinoid receptors by an entourage effect. There are a significant number of prospective and randomized trials demonstrating the pain-relieving effects of PEA. There is lesser evidence of benefit in patients with nonpain symptoms related to depression, Parkinson disease, strokes, and autism. There are no reported drug-drug interactions and very few reported adverse effects from PEA. Further research is needed to define the palliative benefits to PEA.

Mixing Effect of Ligand on Carbon Dioxide Capture Behavior of Zeolitic Imidazolate Framework/Poly(amide-b-ethylene oxide) Mixed Matrix Membranes

Mixed matrix membranes (MMMs) were synthesized from poly(amide-b-ethylene oxide) (Pebax) and mixed-ligand zeolitic imidazolate framework (ZIF-8-90(x)). The separation performance and microstructure of the membranes with different organic linker fractions and ZIF-8-90(x) loadings were characterized. Energy-dispersive X-ray microanalysis and field-emission scanning electron microscopy showed excellent adhesion between Pebax and ZIF-8-90(x), and no voids or clusters were observed. Single gas permeation measurements on MMMs revealed that the CO2/N-2 selectivity of the membranes with ZIF-8-90(x) was better than that of the membrane with ZIF-8. Permeation analysis showed that the membranes with mixed ZIF-8 and ZIF-90 offers a tight microstructure. Overall, this study demonstrated that the gas separation behavior of the Pebax membrane was significantly changed by ZIF-8-90(x) loading. The ZIF-8-90(x)/Pebax membranes can be a good candidate for CO2 capture applications.

The Hancock Alkaloids (-)-Cuspareine, (-)-Galipinine, (-)-Galipeine, and (-)-Angustureine: Asymmetric Syntheses and Corrected H-1 and C-13 NMR Data

The asymmetric syntheses of all members of the Hancock alkaloid family based upon a 2-substituted N-methyl-1,2,3,4-tetrahydroquinoline core are delineated. The conjugate addition of enantiopure lithium N-benzyl-N-(alpha-methyl-p-methoxybenzyl)amide to 5-(o-bromophenyl)-N-methoxy-N-methylpent-2-enamide is used to generate the requisite C-2 stereogenic center of the targets, while an intramolecular Buchwald-Hartwig coupling is used to form the 1,2,3,4-tetrahydroquinoline ring. Late-stage diversification completes construction of the C-2 side chains. Thus, (-)-cuspareine, (-)-galipinine, (-)-galipeine, and (-)-angustureine were prepared in overall yields of 30%, 28%, 15%, and 39%, respectively, in nine steps from commercially available 3-(o-bromophenyl)propanoic acid in all cases. Unambiguously corrected H-1 and C-13 NMR data for the originally isolated samples of (-)-cuspareine, (-)-galipinine, and (-)-angustureine are also reported, representing a valuable reference resource for these popular synthetic targets.

Confined naked gold nanoparticles in ionic liquid films

Surface-clean Au nanoparticles (NPs) confined in films of ionic liquids (ILs) can be easily fabricated by sputtering deposition. A silicon wafer coated with films of both hydrophobic (bis((trifluoromethyl) sulfonyl) amide, NTf2-) and hydrophilic (tetrafluoroborate, BF4-) imidazolium-based ILs forms an ‘ionic carpet-like’ structure that can be easily decorated with Au NPs of 5.1 and 6.5 nm mean diameter, respectively. The depth profile distribution of the Au NPs depends on the arrangement of the IL, which is controlled mainly by the anion volume. Higher concentrations of Au NPs are found closer to the IL surface for the system containing a larger anion (NTf2) whereas Au NPs are located deeper in the IL for the system containing a smaller anion (BF4). The Au NPs are well distributed over the IL/Si support and are strictly confined in a single layer of the IL. This method is among the most simple and versatile for the generation of liquid layers containing surface-clean, stable and confined Au NPs.

Deep purification of seawater using a novel zeolite 3A incorporated polyether-block-amide composite membrane

In this study, a novel hydrophilic-hydrophobic composite membrane was prepared and used in a pervaporative desalination of NaCl-water solution and seawater. For this purpose, polyether block amide (PEBA) was selected as membrane matrix. Zeolite 3A was incorporated to PEBA polymer for facilitating the water permeation through the membrane. The surface morphologies of the pristine and composite membranes were examined by scanning electron microscopy. Thermogravimetric analyses of the pristine and composite membranes were performed by adjusting the zeolite 3A concentration in the PEBA polymer. The effect of the zeolite addition on membrane’s surface hydrophilicity was analyzed using contact angle measurement. Firstly, influences of zeolite content, feed temperature and NaCl concentration on pervaporative desalination performances were performed in the pervaporation of NaCl-water solution. All membranes exhibited excellent performance, and the salt rejection of >99.5% and flux of >2.07 kg m(-2) h(-1) were achieved. Secondly, seawater desalination was performed. Effect of zeolite addition at a given temperature was also investigated. The better salt rejection was obtained as 99.81% accompanied with a very good flux of 4.57 kg m(-2) h(-1) in pervaporative seawater desalination at 40 degrees C using 20 wt.% zeolite 3A incorporated membrane.

A Major Step in Opening the Black Box of High-Molecular-Weight Dissolved Organic Nitrogen by Isotopic Labeling of Synechococcus and Multibond Two-Dimensional NMR

Dissolved organic nitrogen (DON) comprises the largest pool of fixed N in the surface ocean, yet its composition has remained poorly constrained. Knowledge of the chemical composition of this nitrogen pool is crucial for understanding its biogeochemical function and reactivity in the environment. Previous work has suggested that high-molecular weight (high-MW) DON exists only in two closely related forms, the secondary amides of peptides and of N-acetylated hexose sugars. Here, we demonstrate that the chemical structures of high-MW DON may be much more diverse than previously thought. We couple isotopic labeling of cyanobacterially derived dissolved organic matter with advanced twodimensional NMR spectroscopy to open the black box of uncharacterized high-MW DON. Using multibond NMR correlations, we have identified novel N-methyl-containing amines and amides, primary amides, and novel N-acetylated sugars, which together account for nearly 50% of cyanobacterially derived high MW DON. This study reveals unprecedented compositional details of the previously uncharacterized DON pool and outlines the means to further advance our understanding of this biogeochemically and globally important reservoir of organic nitrogen.
