He, Xiaochun published the artcileSynthesis of Unsymmetrical N-Heterocyclic Carbene-Nitrogen-Phosphine Chelated Ruthenium(II) Complexes and Their Reactivity in Acceptorless Dehydrogenative Coupling of Alcohols to Esters, Formula: C8H18O, the main research area is tridentate phosphinophenyliminoimidazolylidene chelated ruthenacycle preparation catalyst dehydrogenative coupling alc; crystal structure tridentate phosphinophenyliminoimidazolylidene chelated ruthenacycle; mol structure tridentate phosphinophenyliminoimidazolylidene chelated ruthenacycle; ester preparation.

Two novel Ru complexes RuH(CO)Cl(PPh3)(κ2-CP) (1) and [fac-RuH(CO)(PPh3)(κ3-CNP)]Cl (2) bearing unsym. N-heterocyclic carbene-N-phosphine (CNP) were synthesized and characterized with 1H NMR, 31P NMR, and HRMS. The structure of complex 2 was further confirmed by single-crystal x-ray diffraction. An anion exchange experiment proved that complex 2 could transform into complex 1 in solution The two complexes exhibited a highly catalytic performance in acceptorless dehydrogenative coupling of alcs. to esters, and the excellent isolated yields of esters were given in a catalyst loading of 1% for para- and meta-substituted benzyl alcs. and long-chain primary alcs. Although some ortho-substituted benzyl alcs. displayed a relatively low reactivity due to the steric hindrance and the coordination of electron donor with the Ru center, the good product yields were still obtained by prolonging the reaction time. Especially, this system successfully realized the dehydrogenative cross-coupling to esters between two different primary alcs.

Kochansky, Jan published the artcileSubstituent effects on chemosterilant activity of 2,4-di-tert-butyl-6-(4′-substituted benzyl)phenols in the house fly (Musca domestica L.), Recommanded Product: (4-Butoxyphenyl)methanol, the main research area is chemosterilant butylbenzylphenol fly structure; Musca chemosterilant butylbenzylphenol structure.

A series of 2,4-di-tert-butyl-6-(4′-X-benzyl)phenols was prepared, analogous to the compound Jurd 2644 (X = OMe) in an attempt to establish a Hammett relationship between the 4′-substituent and the chemosterilant activity of the compounds after oral administration to adult Musca domestica. Fourteen compounds of this type were prepared, 12 of them new. Jurd 2419 (X = H) was found to be as active in our bioassay as Jurd 2644, as were four new compounds [X = N(CH3)2, CH3, SCH3, Cl]. All prevented successful reproduction at 30 mg/kg of diet. There was no correlation between Hammett σ and activity. Active compounds all had small substituents and mol. weights below 350. The activity seemed to be determined by the bulk of X rather than by its electronic properties.

Ding, Meng published the artcileOrderly MOF-Assembled Hybrid Monolithic Stationary Phases for Nano-Flow HPLC, Category: alcohols-buliding-blocks, the main research area is MOF assembled hybrid monolithic stationary phasesnano flow HPLC.

We report an approach that polymerizable handle-modified nanosized metal organic frameworks (MOFs) are used as independent monomers to be covalently organized by crosslinking mols. (CLMs) into an orderly MOF-assembled hybrid monolithic stationary phase, overcoming the resp. problems of previously reported MOF-mixed or embedded stationary phases so far. It has a hierarchical micro-, meso-, and macropore structure throughout the monolithic matrix that is donated from MOF themselves, formed via CLM crosslinking in-between MOFs and expended by porogenic solvents, and a tunable surface chem. derived inherently from MOFs, regulated by CLMs and initiated by the mobile phases as well. Such a pore structure and surface chem. display multiplex interactions of sieving and electrostatic repulsion in addition to the polarity-based interactions that synergistically govern the partitioning way and degree of target mols. between the stationary and mobile phases, thus offering the ability to simultaneously sep. small and large mols. during one chromatog. run on a nano-flow capillary high-performance liquid chromatog. platform. A baseline mutual separation with the HETP and Rs of, for example, 9.2 μm butylbenzene and 4.56 (butylbenzene and pentylbenzene), 7.9 μm (phenylalanine) and 3.50 (tryptophan and phenylalanine), and 7.0 μm (myoglobin) and 1.91 (bovine serum albumin and myoglobin) was achieved when UiO-66/NH-methacrylate was exemplified as a model of MOFs and 1,6-hexanediol dimethacrylate and stearyl methacrylate together as CLMs. Not limited to the MOFs and CLMs demonstrated here, other available MOFs and CLMs or newly designed and synthesized ones are expected to be used for constructing one′s own desired monolithic stationary phases toward her/his particular purposes.

Xie, Ya-Fei published the artcileBifunctional organocatalysts for the conversion of CO2, epoxides and aryl amines to 3-aryl-2-oxazolidinones, Related Products of alcohols-buliding-blocks, the main research area is aryl oxazolidinone preparation; epoxide carbon dioxide aryl amine regioselective ring opening cycloaddition.

A route to synthesize 3-aryl-2-oxazolidinones I (R1 = Me, H2C:CHCH2OCH2, Ph, 4-FC6H4, etc.; R2 = Ph, 1-naphthyl, 2-pyridyl, etc.) through a three-component reaction between CO2, aryl amines R2NH2, and the corresponding 2-R1-substituted epoxides with a binary organocatalytic system composed of organocatalysts II (R3 = R4 = Me; R3 = H, R4 = Me, i-Pr, MeSCH2, Ph, 4-HOC6H4; X = I, Br, Cl) and DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) was developed. The method allows wide scopes of epoxide and aryl amine substrates with various functional groups under mild reaction conditions. The control experiments indicate that a cyclic carbonate is formed via cycloaddition of epoxides with CO2, which further reacts with the β-amino alc. originating from epoxides and aryl amines, resulting in the formation of 3-aryl-2-oxazolidinones.

Guan, Zhipeng published the artcileElectrochemical Oxidative Carbon-Atom Difunctionalization: Towards Multisubstituted Imino Sulfide Ethers, COA of Formula: C4H10OS, the main research area is electrochem oxidative difunctionalization isocyanide imino sulfide ether stereoselective synthesis; electrochemistry; ethers; isocyanides; radicals; synthetic methods.

Ethers (C-O/S) are ubiquitously found in a wide array of functional mols. and natural products. Nonetheless, the synthesis of imino sulfide ethers, containing an N(sp2)=C(sp2)-O/S fragment, still remains a challenge because of its sensitivity to acid. Developed here in is an unprecedented electrochem. oxidative carbon-atom difunctionalization of isocyanides, providing a series of novel multisubstituted imino sulfide ethers. Under metal-free and external oxidant-free conditions, isocyanides react smoothly with simple and readily available mercaptans and alcs. [e.g., 4-fluorobenzenethiol + Et isocyanoacetate + methanol �(Z)-I (80% isolated)]. Importantly, the procedure exhibited high stereoselectivities, excellent functional-group tolerance, and good efficiency on large-scale synthesis, as well as further derivatization of the products.

Russo, Laura published the artcileThiol-ene Mediated Neoglycosylation of Collagen Patches: A Preliminary Study, COA of Formula: C9H16O6, the main research area is thiol ene neoglycosylation collagen patch surface treatment.

Despite the relevance of carbohydrates as cues in eliciting specific biol. responses, the covalent surface modification of collagen-based matrixes with small carbohydrate epitopes has been scarcely investigated. We report thereby the development of an efficient procedure for the chemoselective neoglycosylation of collagen matrixes (patches) via a thiol-ene approach, between alkene-derived monosaccharides and the thiol-functionalized material surface. Synchrotron radiation-induced XPS (SR-XPS), Fourier transform-IR (FT-IR), and enzyme-linked lectin assay (ELLA) confirmed the effectiveness of the collagen neoglycosylation. Preliminary biol. evaluation in osteoarthritic models is reported. The proposed methodol. can be extended to any thiolated surface for the development of smart biomaterials for innovative approaches in regenerative medicine.
