Processing and properties of phenylethynyl-terminated PMDA type polyimide composites

The processing and mechanical properties of a novel PMR type polyimide reinforced with carbon fibers were studied. TriA X matrix resin, which is derived from the reaction of pyromellitic dianhydride (PMDA), 2-pheny-4,4′-diaminodipheny ether (p-ODA) and 4-phenylethynylphthalic anhydride (PEPA), has high toughness and an amorphous structure due to an asymmetric and nonplanar backbone. Satin woven prepreg was produced by coating an alcohol solution of monomers onto de-sized T650-35 fabric. The laminates processed under 1.72 MPa at 371C were fully consolidated, as confirmed by microscopic observations and ultrasonic C-scan. Mechanical properties of TriA X neat resin and T650-35 8HS/TriA X composites were measured at room temperature.

Trifluoromethylation of Secondary Nitroalkanes

Using a commercially available Umemoto’s reagent, the metal-free trifluoromethylation of nitroalkanes is now possible. This method provides a general, high-yielding synthesis of alpha-(trifluoromethyl)nitroalkanes. The quaternary alpha-(trifluoromethyl)nitroalkanes obtained from this transformation can be elaborated to a variety of complex nitrogen-containing molecules, including alpha-(trifluoromethyl)amines.

Synthesis of 1,2-phenylenedimethanols by base-promoted reduction of isobenzofuran-1(3H)-ones with silane

An efficient method for preparation of substituted 1,2-phenylenedimethanols and aliphatic 1,4-diols that are valuable intermediates in organic synthesis, has been developed by the base-promoted reduction of isobenzofuran-1(3H)-ones and gamma-lactones with silane under mild conditions. Compared with traditional procedures using stoichiometric amounts of metal hydrides and alkyl reductants, the present method avoids the use of sensitive reagents and is operationally simple and a broad variety of functional groups are tolerated.

Facile organocatalytic domino oxidation of diols to lactones by in situ-generated TetMe-IBX

The domino oxidation of diols to lactones is an important transformation, and catalytic protocols that allow this conversion smoothly are scarce. Capitalizing on the established reactivity of tetramethyl-IBX (TetMe-IBX) and its in situ generation in the presence of a co-oxidant, such as oxone, we have shown that a variety of diols can be converted to the corresponding lactones in respectable yields by employing the precursor of TetMe-IBX, namely, tetramethyl-o-iodobenzoic acid (TetMe-IA), as a catalyst in 5 mol % in the presence of 2 equiv of oxone.

Structural studies on cycloadducts of furan, 2-methoxyfuran, and 5-trimethylsilylcyclopentadiene with maleic anhydride and N-methylmaleimide

(Chemical Equation Presented) The early stages of the retro-Diels-Alder reaction are clearly apparent in the structures of the cycloadducts formed between furan or 5-trimethylsilylcyclopentadiene with maleic anhydride and N-methylmaleimide. The degree of lengthening of the C-C bonds that break in this reaction is clearly related to the known reactivity of these cycloadducts toward this reaction. In the structures of the cycloadducts 21 and 22 derived from 2-methoxyfuran, the early stages of an alternative fragmentation reaction are apparent, consistent with the reactivity of these compounds in solution.

Synthesis of Enantioenriched Phthalide and Isoindolinone Derivatives from 2-Formylbenzoic Acid

Transformations of 2-formylbenzoic acid provide direct access to a series of heterocyclic organic compounds such as phthalides and isoindolinones. Here, we use (+)-cinchonine as a catalyst in conjunction with nonafluoro-tert-butanol as a hydrogen-bond donor to afford enantiomerically enriched acylated 3-hydroxyphthalides with up to 99% yield and 90% ee through dynamic kinetic resolution. Moreover, various 3-alkoxyphthalides as well as 2-alkyl-3-hydroxy-1-isoindolinones were synthesized from 2-formylbenzoic acid.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 16859-59-9, you can also check out more blogs about16859-59-9

Novel Terminal Bipheny-Based Diapophytoene Desaturases (CrtN) Inhibitors as Anti-MRSA/VISR/LRSA Agents with Reduced hERG Activity

CrtN has been identified as an attractive and druggable target for treating pigmented Staphylococcus aureus infections. More than 100 new compounds were synthesized, which target the overwhelming the defects of the CrtN inhibitor 1. Analogues 23a and 23b demonstrated a significant activity against pigmented S. aureus Newman and 13 MRSA strains (IC50 = 0.02-10.5 nM), along with lower hERG inhibition (IC50 > 30 muM, ?10-fold decrease in comparison with 1). Furthermore, 23a and 23b were confirmed to reduce the staphylococcal load in the kidney and heart in a mouse model with normal treatment deeper than pretreatment ones, comparable even with vancomycin and linezolid. Remarkably, 23a could strongly block the pigment biosynthesis of these nine multidrug-resistant MRSA strains, including excellent activity against LRSA strains and VISA strains in vivo, and all of which demonstrated that 23a has a huge potential against intractable MRSA, VISA, and LRSA issues as a therapeutic drug.

Distribution and migration study of pesticides between peel and pulp in grape by online gel permeation chromatography-gas chromatography/mass spectrometry

A multi-residue method for the analysis of 175 pesticides was developed by online gel permeation chromatography-gas chromatography/mass spectrometry (GPC-GC/MS) to study pesticide distribution and migration between peel and pulp in grape. The separated peel and pulp samples were extracted by acetonitrile after fortified with chlorpyrifos-d10 isotope internal standard. The extract was first purified by solid phase distribution sorbent of primary secondary amine (PSA) and then detected by online GPC-GC/MS. At the spiking levels of 10, 50 and 200 mug kg-1, 73.7%, 94.3% and 98.9% of the pesticides, respectively, presented recoveries between 70% and 120%. The ratios were 91.4%, 94.9% and 92.0%, respectively, for the relative standard deviations (RSDs) bellow 15%. Limits of detection (LODs) for the pesticides in pulp were below 10 mug kg-1. Pesticides were separated to four groups according to the distribution ratios (peel/whole grape) of 100%, 80-99.9%, 50-80% and 0-50% in peel. Relationship between the pesticide distribution and corresponding regulation of EU maximum residue level (MRL) was discussed. Six factors influencing the pesticides distribution and migration between peel and pulp were discussed. Weak linear correlation between the pesticide solubility in water (20 C) and the distribution ratios (lowest and average) in peel was found for most of the detected pesticides with solubility less than 200 mg L-1.
