Porous polyolefin membranes play an integral role in lithium-ion battery technology as the barrier preventing direct anode and cathode contact. Block polymers containing a sacrificial component have proven to be attractive precursors for nanoporous polymer membranes stemming from their unique ability to self-assemble into mesoscopically organized structures. Selective removal of the sacrificial component can leave a scaffold with well-controlled pore dimensions and porosity. This communication describes the synthesis of block polymers containing polylactide (PLA) as the sacrificial component and perfectly linear polyethylene (LPE) as the matrix phase using a combination of ring-opening polymerizations. Bicontinuous morphologies accessible over a broad composition range allow for ready tailoring of porosity. Removal of the PLA results in semicrystalline LPE with an interpenetrating void space having pore dimensions less than 100 nm. The porosity and domain size dependence on composition was corroborated by nitrogen adsorption and scanning electron microscopy. The mechanical robustness of the nanoporous samples was confirmed by tensile testing. The outstanding chemical resistance of the nanoporous LPE samples was demonstrated by treatment with concentrated strong acids over extended periods (?1 day).

The synthesis of a triglycosylated helical foldamer based on a combination of cyclopentyl- and pyrrolidinyl-based amino acids is described. This structure is stable in water, maintaining as it does a series of carbohydrate units in proximity to one another, and represents the basis of a new approach to the study of carbohydrate-carbohydrate interactions.

Catalytic transformation of renewable feedstocks into fine chemicals is in high demands and olefin metathesis is a sophisticated tool for biomass conversion. Nevertheless, the large-scale viability of such processes depends on the conversion efficiency, energy efficiency, catalytic activity, selective conversion into desired products, and environmental footprint of the process. Therefore, conversions of renewables by using simple, swift, and efficient methods are desirable. A microwave-assisted ethenolysis and alkenolysis (using 1,5-hexadiene) of canola oil and methyl esters derived from canola oil (COME) and waste/recycled cooking oil (WOME) was carried out by using ruthenium-based catalytic systems. A systematic study using 1st and 2nd generation Grubbs and Hoveyda?Grubbs catalysts was carried out. Among all ruthenium catalysts, 2nd generation Hoveyda?Grubbs catalyst was found to be highly active in the range of 0.002?0.1 mol % loading. The conversions proved to be rapid providing unprecedented turnover frequencies (TOFs). High TOFs were achieved for ethenolysis of COME (21 450 min?1), direct ethenolysis of canola oil (19 110 min?1), for WOME (15 840 min?1) and for cross-metathesis of 1,5-hexadiene with COME (10 920 min?1). The ethenolysis of commercial methyl oleate was also performed with a TOF of 8000 min?1 under microwave conditions.

Combining bio- and chemocatalysts for chemoenzymatic reaction sequences is of high interest to organic chemistry. In this study, we combined a ring-closing metathesis reaction conducted by a Grubbs? catalyst and a subsequent enzymatic ester hydrolysis reaction conducted by pig liver esterase within a two-step one-pot process. We addressed sustainability by encapsulating both catalysts in biopolymer-based hydrogels derived from renewable resources to allow straightforward recycling and using aqueous media for the reactions. When we investigated the approaches of either conducting the reaction sequence in the same solvent for both reactions or using different preferred solvents for each reaction, the enzyme activity turned out to be enhanced when encapsulating the enzyme, thus shielding it from the Grubbs? catalyst. In terms of recycling, the encapsulated catalysts demonstrated promising performance with >80 % conversion for seven runs.

Macrocyclic natural products have been recognized and utilized as new platforms for designing drugs in pharmaceutical research because the constrained three-dimensional shapes and the large surface areas of these complex structures enable selective binding to conventionally undruggable targets. Since natural products are not necessarily ideal for medicinal use, structural optimization is required to obtain superior drug candidates. However, the modifications to macrocyclic natural products that will afford the best pharmacological characteristics cannot be known a priori. Therefore, this optimization procedure requires the exploration of a vast array of natural product analogues to identify new compounds with more desirable properties. To fully explore the chemical space around complex macrocyclic natural products, the construction of a large number of analogues is required. In this review, we provide an overview of the efficient synthetic construction of the analogues of macrocyclic natural products and the evaluation of their biological activities. The examples of the comprehensive structure-activity relationship (SAR) studies depicted herein led to the discoveries of biologically useful analogues. These studies illustrate the importance of designing building blocks and coupling strategies to synthesize a variety of natural product based analogues.

By natural product inspired diversity-oriented synthesis, we had developed a new class of selective antagonist, IKM-159, for the AMPA receptor. Here, we report syntheses of IKM-159 and skeletally diverse five analogues in racemic forms, two of which are heterotricycles and the other three compounds are truncated analogues, to study the structure-activity relationships. The key reactions are two domino reactions including Ugi/Diels-Alder reaction and domino metathesis reaction. An exceptionally high level of regiocontrol in the cross metathesis reaction is also reported. Georg Thieme Verlag Stuttgart New York.

Efficient trans-hydroarylation of alkynes by simple arenes has been realized regio- and stereoselectively at room temperature in the presence of Pd(II) or Pt(II) catalysts and a mixed solvent containing trifluoroacetic acid (TFA). Various arenes undergo trans-hydroarylation selectively across terminal and internal C – C triple bonds – including those conjugated to CHO, COMe, CO2H, and CO2Et groups, affording kinetically controlled cis-arylalkenes predominantly in most cases, especially, in good yields for electron-rich arenes and activated alkynes. The formation of arene/alkyne 1/2 or 2/1 adducts as side products is dependent on the arenes’ and alkynes’ substituents, which can be suppressed in some cases by changing the catalyst, catalyst concentration, and reaction time. The Pt(II) system, PtCl2/2AgOAc/TFA, shows lower catalytic activity than Pd(OAc)2/TFA, but higher selectivity, giving higher yields of adducts at the same conversion. On the basis of several isotope experiments and control reactions, a possible mechanism involving electrophilic metalation of aromatic C – H bonds by in-situ-generated cationic Pd(II) and Pt(II) species leading to intermolecular trans-arylpalladation to alkynes has been discussed.

Reactions between HRuCl(PPh3)3 and 1,3- or 1,5-cyclooctadiene yield the 1,2-dihydropentalenyl complex (eta5-C8H9)Ru(PPh3) 2Cl through a series of steps including olefin insertion and electrocyclization. The reaction is accompanied by the loss of two equivalents of hydrogen. The product crystallizes in the monoclinic space group P1? (No. 2). (eta5-C8 H9)Ru(PPh3)2Cl catalyzes the dimerization of phenylacetylene to a ?2:1 mixture of Z: E 1,4-diphenyl-1-buten-3-yne. Comparison of the catalytic activity of (eta5-C8H9)Ru(PPh3) 2Cl with (eta5-C5H5) Ru(PPh3)2Cl, (eta5-C5 Me5)Ru(PPh3)H3 and {eta5 -HB(pz)3}Ru(PPh3)2Cl suggests that the more electron-rich eta5 ligands favor formation of the Z isomer.
