Targeted development of hydrophilic porous polysulfonamide gels with catalytic activity

We report the use of a template and functional monomers in the synthesis of three novel polysulfonamide gels with new architectures and functional groups. These mesoporous polysulfonamide gels were prepared by the condensation polymerization of benzene-1,3-disulfonyl chloride (as the main precursor), linear monomers, and cross-linkers (as variable precursors) in the presence of a silica template by a combination of sol-gel chemistry and the nanocasting technique. In this synthesis pathway, in situ polymerization onto the template surface led to the construction of a silica/polymer nanocomposite. Next, after removal of the template, the nanocomposite gels were transformed into mesoporous polysulfonamide nanospheres. After the physicochemical identification of the synthesized materials, functionalized polysulfonamides were used as reusable novel catalysts with high efficiency for the Strecker reaction under mild conditions. These polymers have Brunsted/Lewis acid active sites, a mesoporous structure, and hydrogen bonding. Moreover, since these polymers are hydmgels that can absorb water, they can promote the Strecker reaction through chemical absorption of the generated water as a driving force. Overall, this article describes a novel synthesis procedure and application of porous polysulfonamide gels.

X-band rapid-scan EPR of nitroxyl radicals

X-band rapid-scan EPR spectra were obtained for dilute aqueous solutions of nitroxyl radicals N-15-mHCTPO (4-hydro-3-carbamoyl-2,2,5,5-tetra-perdeuteromethyl-pyrrolin-1-N-15-oxyl-d(12)) and N-15-PDT (4-oxo-2,2,6,6-tetra-perdeuteromethyl-piperidinyl-N-15-oxyl-d(16)). Simulations of spectra for N-15-mHCTPO and N-15-PDT agreed well with the experimental spectra. As the scan rate is increased in the rapid scan regime, the region in which signal amplitude increases linearly with B-1 extends to higher power and the maximum signal amplitude increases. In the rapid scan regime, the signal-to-noise for rapid-scan spectra was about a factor of 2 higher than for unbroadened CW EPR, even when the rapid scan spectra were obtained in a mode that had only 4% duty cycle for data acquisition. Further improvement in signal-to-noise per unit time is expected for higher duty cycles. Rapid scan spectra have higher bandwidth than CW spectra and therefore require higher detection bandwidths at faster scan rates. However, when the scan rate is increased by increasing the scan frequency, the increase in noise from the detection bandwidth is compensated by the decrease in noise due to increased number of averages per unit time. Because of the higher signal bandwidth, lower resonator Q is needed for rapid scan than for CW, so the rapid scan method is advantageous for lossy samples that inherently lower resonator Q.

A review on pyrolysis of protein-rich biomass: Nitrogen transformation

Pyrolysis of protein-rich biomass, such as microalgae, macroalgae, sewage sludge, energy crops, and some lignocellulosic biomass, produces bio-oil with high nitrogen (N) content, sometimes as high as 10 wt% or even higher. Major nitrogenous compounds in bio-oil include amines/amides, N-containing heterocycles, and nitriles. Such bio-oil cannot be used as fuel directly since the high N content will induce massive emission of nitrogen oxides during combustion. The present review comprehensively summarized the effects of biomass compositions (i.e., elemental, biochemical, and mineral compositions) and pyrolysis parameters (i.e., temperature, heating rate, atmosphere, bio-oil collection/fractionation methods, and catalysts) on the contents of N and the N-containing chemical components in bio-oil. The migration and transformation mechanisms of N during the pyrolysis of biomass were then discussed in detail. Finally, the research gaps were identified, followed by the proposals for future investigations to achieve the denitrogenation of bio-oil.

Studies on lower epidermal papillae, the site of storage of basmati rice aroma compounds in Pandanus amaryllifolius Roxb

Pandanus amaryllifolius Roxb. is the only species belonging to the family Pandanaceae that has fragrant leaves. In the higher plants, aroma compounds in leaves are stored in vacuoles and epidermal outgrowths like papillae, glandular hairs and trichomes. The lower epidermis of P. amaryllifolius has papillae as protrusions of lower epidermal cells. The papillae run parallel along the leaf length and are absent over the veins and midrib. The number of papillae varied from one to seven per cell. Papillae were also found surrounding the stomata forming a necklace-like structure. Quantitative analysis yielded 3.10 mg of 2-acetyl-1-pyrroline per kg of fresh leaves. Cell size, area and number of papillae were more in the clone of ‘Sawantwadi’ than in ‘Pune’.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 636-41-9 is helpful to your research. Recommanded Product: 636-41-9.

Recent Developments in Radical Cross-Coupling of Redox-Active Cycloketone Oximes

Recent years have witnessed a renaissance of radical cross-coupling of cycloketone oximes which served as active cyanoalkyl radical via ring fragmentation in various transformations. It provided an efficient and practical strategy to introduce cyanoalkyl groups into organic compounds without using toxic cyanide sources. In this review, a comprehensive overview of recent advances in the field of redox-active cycloketone oximes-based cross-couplings were covered. This review was categorized into two broad parts: non-photocatalyzed and photocatalyzed cross-couplings according to the reaction conditions. Moreover, the two broad parts were further divided into several sub-sections depending on the nature of the bond formation. Some representative examples along with reaction mechanisms were also discussed. 1. Introduction 2. Transition-Metal Catalyzed Cross-Coupling Reactions 2.1. C(sp(3))-C(sp(3)) Bond Formation 2.2.

Design and synthesis of a competent pyrrolinone-peptide hybrid ligand for the class II major histocompatibility complex protein HLA-DR1

The design and synthesis of two pyrrolinone-peptide hybrid ligands (3 and 20) for the rheumatoid arthritis-associated class II MHC HLA-DR1 protein are described. The hybrids incorporate bispyrrolinones 4 and 21 as tetrapeptide mimics for amino acids VKQN (residues 309-312) of the virus hemagglutinin peptide HA 306-318 (PKYVKQNTLKLAT). Ligand construction employed our polypyrrolinone synthetic protocol, in conjunction with Fmoc-based solid-phase peptide synthesis. Bioaffinity studies reveal that hybrid ligand 3 bound the HLA-DR1 protein with affinity (IC50 = 137 nM) comparable to those of both the native HA 306-318 peptide (IC50 = 89 nM) and a control peptide (IC50 = 176 nM). This result demonstrates that the polypyrrolinone scaffold can be employed in the construction of bioactive peptide hybrid ligands, thus considerably expanding the scope and utility of the pyrrolinone scaffold.

Synthesis of spin-labeled RNAs for long range distance measurements by PELDOR

Site directed spin labeled RNA duplexes with different interspin distances were synthesized. The radical 2,2,5,5-tetramethyl-pyrrolin-1-yloxyl-3-acetylene (TPA) was introduced during the solid-phase synthesis through a Sonogashira cross-coupling with 5-iodo-uridine. T-m and CD studies showed that the spin label does not to disturb significantly the A-form of these duplexes. 4-Pulse Electron Double Resonance (PELDOR) was then used to measure intramolecular spin-spin distances of 19.3, 33.0 and 40.9 angstrom, which are in very good agreement with the calculated values of 17 6 32.1 and 39.1 angstrom, obtained from Molecular Dynamics (MD) simulations.
