N-Aryl/alkyl 3-carbonylpyrroles are ubiquitous in compounds of biol. and material significance, whereas their synthesis traditionally requires a multistep protocol. Herein, a kalinite catalyzed direct synthesis of N-substituted 3-carbonylpyrroles from a 2,2-dimethoxyacetaldehyde derived Morita-Baylis-Hillman acetate and a primary amine in ethanol is developed. This reaction is scalable and also applicable to the synthesis of JMH-030, JMC-2004 and other bioactive compounds In the experiment, the researchers used many compounds, for example, 2,5-Dimethoxytetrahydrofuran(cas: 696-59-3Quality Control of 2,5-Dimethoxytetrahydrofuran)

And the article was published in ACS Nano in 2019. Reference of 2,5-Dimethoxytetrahydrofuran The author mentioned the following in the article:

We present a method for a bottom-up synthesis of atomically thin graphene sheets with tunable crystallinity and porosity using aromatic self-assembled monolayers (SAMs) as mol. precursors. To this end, we employ SAMs with pyridine and pyrrole constituents on polycrystalline copper foils and convert them initially into mol. nanosheets-carbon nanomembranes (CNMs)-via low-energy electron irradiation induced crosslinking and then into graphene monolayers via pyrolysis. As the nitrogen atoms are leaving the nanosheets during pyrolysis, nanopores are generated in the formed single-layer graphene. We elucidate the structural changes upon the crosslinking and pyrolysis down to the at. scale by complementary spectroscopy and microscopy techniques including X-ray photoelectron and Raman spectroscopy, LEED, at. force, helium ion, and high-resolution transmission electron microscopy, and elec. transport measurements. We demonstrate that the crystallinity and porosity of the formed graphene can be adjusted via the choice of mol. precursors and pyrolysis temperature, and we present a kinetic growth model quant. describing the conversion of mol. CNMs into graphene. The synthesized nanoporous graphene monolayers resemble a percolated network of graphene nanoribbons with a high charge carrier mobility (∼600 cm2/(V s)), making them attractive for implementations in electronic field-effect devices.

Novel multi-walled carbon nanotubes coated with poly[N-(ferrocenyl formacyl) pyrrole] (MWCNTs@PFFP) nanocomposites were prepared through the in situ oxidation polymerization reaction of N-(ferrocenyl formacyl) pyrrole in the presence of MWCNTs. The MWCNTs@PFFP nanocomposites were characterized by FT-IR, Raman, TGA, XRD, XPS, SEM and TEM techniques. The MWCNTs@PFFP nanocomposites were fabricated into novel electrochem. sensors for simultaneous determination of ascorbic acid (AA), dopamine (DA) and uric acid (UA). The electrochem. behavior of the MWCNTs@PFFP/GCE sensors was examined, and the parameters that influence electrochem. signals were optimized. The exptl. results showed that the fabricated modified electrode sensors exhibited good sensitivity, selectivity, specificity, repeatability and a long lifetime, remaining the initial current of at least 92.5% after 15 days storage in air. The sensors possessed a linear response concentration range over 200-400 muM for AA, 2-16 muM for both DA and UA, and a limit of detection as low as 40.0, 1.1 and 7.3 x 10-1 muM for AA, DA and UA, resp. They are expected to be used as a potential tool for the simultaneous detection of DA, AA and UA in the human body.

The article was titled 《The structure modification of seven-membered aza-brigded neonicotinoids in order to investigate their impact on honey bees》.Name: 2,5-Dimethoxytetrahydrofuran The article contains the following contents:

In order to explore the relationship between the structure and the toxicity to honey bees of seven-membered aza-bridged neonicotinoids, 16 novel seven-membered aza-bridged neonicotinoid analogs are synthesized by replacing the pyridine ring, and changing the substituents on the pyridine ring, the electron-withdrawing group NO2 and the imidazole ring of authors’ previously developed aza-bridged neonicotinoid 1-[(6-chloropyridin-3-yl)methyl]-10-(2,5-dimethylphenyl)-9-nitro-2,3,5,6,7,8-hexahydro-1H-5,8-epiminoimidazo azepine. The insecticidal bioactivities against cowpea aphid (Aphis craccivora) and the bee toxicities of these compounds are tested. Some of the title compounds present good insecticidal activities against cowpea aphid. The results also show that some of the title compounds exhibit lower bee toxicity than that of 1-[(6-chloropyridin-3-yl)methyl]-10-(2,5-dimethylphenyl)-9-nitro-2,3,5,6,7,8-hexahydro-1H-5,8-epiminoimidazo azepine and imidacloprid.
