Approach to Tertiary-Type beta-Hydroxyl Carboxamides Through Sc(OTf)(3)-Catalyzed Addition of Ynamides and Ketones

An efficient approach to access functionalized tertiary-type beta-hydroxyl carboxamides has been developed through Sc(OTf)(3)-catalyzed addition of ynamides and substituted ketones. Water was found to be an important reaction substrate, and the solvent was not needed in this process. A broad range of substituted ynamides and ketones was well applicable to the reaction with excellent chemical selectivities. Moreover, several chiral beta-hydroxyl carboxamides 3j-3r were prepared with excellent regioselectivities and outstanding diastereoselectivities.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 68076-36-8, you can contact me at any time and look forward to more communication. Category: amides-buliding-blocks.

Improved spinnability of PA 6 solutions using AC electrospinning

The experiment addressed the alternating current (AC) electrospinning of polyamide 6 (PA 6) solutions composed of organic acids, which are commonly employed in direct current (DC) electrospinning systems. Initial testing revealed that it is not possible to AC spin ordinary PA 6 solutions so as to provide a product that can be used in subsequent material experiments. The solutions were enriched with oxoacids, which led to the improvement of the spinning process. The solutions were tested by means of both a viscometer and conductivity meter. The layers so produced were scanned using a SEM microscope. Each of the materials was analyzed for the purpose of the provision of statistical data. (C) 2020 Elsevier B.V. All rights reserved.

Copper-Catalyzed Transsulfinamidation of Sulfinamides as a Key Step in the Preparation of Sulfonamides and Sulfonimidamides

Secondary or tertiary sulfinamides are prepared by copper-catalyzed transsulfinamidation of primary sulfinamides with O-benzoyl hydroxylamines. Subsequent oxidations of the resulting products lead to the corresponding sulfonamides. Treatment of N-aryl sulfinamides with O-benzoyl hydroxylamines under copper catalysis provides N-aryl sulfonimidamides.

Functional polymer microspheres as turn-off chemosensors for detection of copper cations

Functional polymer microspheres with fluorescent carbazole unit and various functional groups, such as amide, pyridyl, and imidazole, were prepared by distillation precipitation copolymerization of divinylbenzene (DVB) as a crosslinker, N-vinylcarbazole (NVCz), together with acrylamide (AAm), 4-vinylpyridine (VPy), and 1-vinylimidazole ((VIM) as functional monomers in acetonitrile in the absence of any stabilizer. The resultant polymer microspheres were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), UV-Vis spectroscopy, photoluminescent spectroscopy, inductively coupled plasma (ICP), and X-ray photoelectron microscopy (XPS). The functional polymer microspheres acted as a turn-off chemical sensor with excellent stability for determination of copper cation (Cu2+) in methanol via the quenching effect of fluorescence after adsorption of Cu2+ from the solution through the capture ability of functional groups, such as pyridyl, imidazole, and amide on the surface of polymer microspheres. A good linear relationship was set up between the photoluminescence intensity at the emission peak of 352 nm and the Cu2+ concentrations ranging from 0 to 1.0 mu M with the presence of pyridyl group as a ligand. The effects of the functional groups were investigated on the fluorescent response for the microspheres as chemical sensors.

1,3-Dibromo-5,5-dimethylhydantoin mediated oxidative amidation of terminal alkenes in water

A variety of terminal alkenes were converted to the corresponding amides in yields of 25 to 86% in water via treatment with 1,3-dibromo-5,5-dimethylhydantoin, followed by reaction with molecular iodine and aq. NH3 (or amine) in one pot. This metal-and organic solvent-free protocol is not only suitable for styrene derivatives, but also, for the first time, works well on terminal aliphatic alkenes.

Increase in furfural tolerance by combinatorial overexpression of NAD salvage pathway enzymes in engineered isobutanol-producing E. coli

To reduce the furfural toxicity for biochemical production in E. coli, a new strategy was successfully applied by supplying NAD(P) H through the nicotine amide salvage pathway. To alleviate the toxicity, nicotinamide salvage pathway genes were overexpressed in recombinant, isobutanol-producing E. coli. Gene expression of pncB and nadE respectively showed increased tolerance to furfural among these pathways. The combined expression of pncB and nadE was the most effective in increasing the tolerance of the cells to toxic aldehydes. By comparing noxE-and fdh-harbouring strains, the form of NADH, rather than NADH, was the major effector of furfural tolerance. Overall, this study is the application of the salvage pathway to isobutanol production in the presence of furfural, and this system seems to be applicable to alleviate furfural toxicity in the production of other biochemical.

Crystal-to-crystal transformation and linker exchange in Cd(II) coordination polymers based on flexible bis-pyridyl-bis-amide and 1,4-naphthalenedicarboxylate

Solvothermal reactions of Cd(ii) salts and naphthalene-1,4-dicarboxylic acid (1,4-H2NDC) with bis(N-pyrid-3-ylmethyl)adipoamide, L-1, and bis(N-pyrid-3-ylmethyl)suberoamide, L-2, afforded three Cd(II) coordination polymers, {[Cd(L-1)(1,4-NDC)(H2O)]center dot H2O}(n), 1, {[Cd(L-2)(1,4-NDC)]center dot 2H(2)O}(n), 2, and {[Cd-2(L-2)(1,4-NDC)(2)]3H(2)O}(n), 3, which have been structurally characterized using single-crystal X-ray crystallography. Complex 1 forms a 2D layer with 4(4)-sql topology, whereas 2 and 3 are 3D frameworks with rare {3(2)center dot 6(2)center dot 7(2)}{3(2)center dot 6(5)center dot 7(3)}(2)-4,5T61 and unique {3(2)center dot 5(4)}{3(4)center dot 4(6)center dot 5(8)center dot 6(6)center dot 7(4)}-sqc776 topologies, respectively. Complex 2 undergoes reversible crystal-to-crystal transformation to 3, while irreversible structural transformations from 1 to 2 and 3 to 1 can be carried out by linker exchange. Reorientation of the amide oxygen atoms that results in the change of the ligand conformation is proposed for the initiation of the crystal-to-crystal transformation. Complex 3 represents a unique example of a coordination polymer that is able to undergo both crystal-to-crystal transformation and linker exchange.

Effect of Growth Hormone (GH) and Resistance Training on the Collagen Properties of Femoral Bone Tissue

The indiscriminate use of anabolic steroids in gyms has been growing in a generalized way, among which, the most common is growth hormone (GH). In the short term GH may potentiate muscle growth, especially when taken in combination with resistance training. However, the effects of this hormone are not yet fully understood in the literature, especially in relation to collagen properties. The objective of this study was to evaluate the effect of the application of growth hormone (GH) and resistance training (RT) on the collagen properties of femoral bone tissue using Raman Spectroscopy. In this study 40 male rats were randomly distributed into four groups (n=10): control (C), control and GH application (GH), resistance training (T), and resistance training and GH application (GHT). The training consisted of four series of 10 water jumps, performed three times a week, with an overload corresponding to 50 % of body weight and duration of four weeks. GH was applied at a dosage of 0.2 IU/Kg (0.067 mg/kg) to each animal, three times a week, every other day. The animals were euthanized and the right femurs were collected for analysis of bone structure. Raman spectroscopy (RS) was used to observe the following compounds from their respective bands: type I collagen (662 cm(-1)), amide III (1243 cm(-1)), proteins including type I collagen (1278 cm(-1)), woven collagen (1322 cm(-1)), association of collagen, phospholipids, nucleic acid, and phosphate (1330 cm(-1)), and collagen and protein deformation (1448 cm(-1)). The results demonstrated an increase in the collagen properties in all analyzed variables, however, the T group presented a statistically significant difference (p<0.05). It is possible to conclude that isolated physical training was shown to be more efficient than when combined with the application of GH to increase the collagen properties of the femoral bone tissue. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.
