Electrophilic bromination of pyrroles bearing carbonyl substituents at C-2 typically results in a mixture of the 4- and 5-brominated species, generally favoring the 4-position. Herein, it is describe a substrate-controlled regioselective bromination in which tetra-Bu ammonium tribromide (TBABr3) reacts with pyrrole-2-carboxamide substrates to yield the 5-brominated species as the predominant (up to >10:1) product.

Ionescu, Andreea; Lento, Raffaella; Mastropietro, Teresa F.; Aiello, Iolinda; Termine, Roberto; Golemme, Attilio; Ghedini, Mauro; Bellec, Nathalie; Pini, Elena; Rimoldi, Isabella; Godbert, Nicolas published the artcile< Electropolymerized Highly Photoconductive Thin Films of Cyclopalladated and Cycloplatinated Complexes>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is phenylpyridine cycloplatinated cyclopalladated Schiff base preparation electropolymerized photoconductive film; cyclopalladated cycloplatinated phenylpyridine Schiff base complex preparation electropolymerized film; electropolymerization; palladium(II) complexes; photoconductivity.

The complete characterization of novel electropolymerizable organometallic complexes is presented. These are newly synthesized cyclometalated complexes of general formula (PPy)M(O^N)n (H(PPy) = 2-phenylpyridine, M = Pd(II) or Pt(II), H(O^N)n = Schiff base). Polymeric thin films have been obtained from these complexes by electropolymerization of the triphenylamino group grafted onto the H(O^N)n ancillary ligand. The redox behavior and the photoconductivity of both of the monomers (PPy)M(O^N)n and the electropolymerized species have been investigated. The polymeric films of (PPy)M(O^N)n have shown a very significant enhancement of photoconductivity when compared to their monomeric amorphous counterparts. The high stability of the obtained films strongly suggests that electropolymerization of cyclometalated complexes represents a viable deposition technique of quality thin films with improved photoconduction properties, hence opening the door to a new class of materials with suitable properties for optoelectronic applications.

Highly enantioselective [2,3]-Wittig rearrangement of functionalized allyl benzyl ethers (E)-ArCH2OCH2C(OSi-iPr3):CHMe [Ar = Ph, 4-MeOC6H4, 3,5-(MeO)2C6H3, etc.] was accomplished using a chiral di-tert-Bu bis(oxazoline) ligand. The reaction proceeded with excellent diastereo- and enantioselectivity when no methoxy substituent was present at the ortho-position on the benzyl group. On the other hand, the enantioselectivity was drastically decreased in the presence of an ortho-methoxy group.

Hao, Zhonglin; Sekkath Veedu, Janeesh published the artcile< Current Strategies for Extensive Stage Small Cell Lung Cancer Beyond First-line Therapy>, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is review small cell lung cancer therapy drug combination; Molecular target; Small cell lung cancer; refractory, relapsed; strategy; treatment.

A review. Extensive stage small cell lung cancer carries extremely poor prognosis and adding immune checkpoint inhibitor to platinum etoposide combination in first line only improved outcomes modestly. Once disease recurs, treatment response is only transient in nature. Various strategies that are being explored include dual checkpoint blockade, BiTE and CAR-T cell approaches. Immune checkpoint inhibitors are being combined with PARP inhibitors. Other approaches currently being investigated include liposomal irinotecan and combining known active agents for SCLC in relapsed setting such as newly approved lurbinectedin with doxorubicin, paclitaxel, irinotecan or topotecan with ATR inhibitor (Berzosertib). Temozolomide has also been tested in combination with a Parp inhibitor. New antibody or small mol. drug conjugates are being actively investigated, so is a biomarker based approach. Better understanding of small cell lung cancer disease biol. via high through-put genomic, proteomic and methylation profiling offer glimpse of hope in our efforts to contain this deadly disease. A table of representative mol. targets under investigation is provided in the end.

Swiderska, Aleksandra; Parzuchowski, Pawel G.; Zurowski, Radoslaw; Wieclaw-Midor, Anna; Wolosz, Dominik published the artcile< Energy dissipating poly(hydroxyurethane) elastomers - Synthesis, characterization and comparison with shear thickening fluid materials>, COA of Formula: C19H34O2, the main research area is polyhydroxyurethane elastomer shear thickening fluid.

In this article we report preparation and characterization of cross-linked non-isocyanate poly(hydroxyurethane) polymeric materials showing energy-dissipating properties. The materials were obtained by the ring-opening polyaddition reaction of hyperbranched multi(cyclic carbonate) (HBPG2) with various diamines. The hyperbranched multi(cyclic carbonate) was obtained in two step procedure including anionic polymerization of glycidol with trimethylolpropane (TMP) as a core yielding polyglycerol (HBPG1) and reaction of terminal vicinal hydroxyl groups of HBPG1 with di-Me carbonate in the presence of potassium carbonate. HBPG1 and HBPG2 were characterized using various NMR techniques, FTIR and MALDI-ToF mass spectroscopy. Thermal and mech. properties of elastomers, including dissipated energy capacity have been studied. Anal. of force absorbing efficiency test results showed that synthesized elastomers have the capability to dissipate about 60% of the energy. The energy dissipating properties of obtained poly(hydroxyurethane) elastomers were similar to those of shear thickening fluid materials that are currently used in human body protectors, in vibration damping devices or sound insulations. The article proves that it is possible to obtain advanced engineering materials using environmentally friendly materials.

Li, Zheng; Tian, Zhongliang; Zhang, Chengzhi; Wang, Fei; Ye, Chong; Han, Fei; Tan, Jun; Liu, Jinshui published the artcile< An AlCl3 coordinating interlayer spacing in microcrystalline graphite facilitates ultra-stable and high-performance sodium storage>, Computed Properties of 112-63-0, the main research area is aluminum chloride microcrystalline graphite facilitate performance sodium storage.

Metal chloride-intercalated graphite intercalation compounds (MC-GICs) show a perfect sandwich structure with high electronic conductivity and chem. stability, but there are few applications for MC-GICs in anode materials of sodium ion batteries (SIBs). Herein, we selected a splendid host microcrystalline graphite (MG) to synthesize an AlCl3 intercalated MG intercalation compound (AlCl3-MGIC) anode material and demonstrated that it is suitable for SIBs via electrolyte optimization. The AlCl3-MGIC electrode is primarily compared in four electrolytes. Sodium storage is proposed for co-intercalation and conversion reactions by simultaneously selecting a compatible NaPF6/diethylene glycol di-Me ether (DEGDME) electrolyte. As a result, the AlCl3-MGIC anode delivers a specific capacity of 202 mA h g-1 at a c.d. of 0.2 A g-1 after 100 cycles and still exhibits a satisfactory capacity of 198 mA h g-1 after 900 cycles. D. functional theory calculations further illustrate that DEGDME solvent mols. offer moderate adsorption energy to sodium ions that guarantees structure stabilization of GICs during repeated cycling. This work provides a theor. basis for designing sodium ion storage with a graphite layered structure and unveiling the prospects of MC-GIC materials as high-performance anodes.

Ma, Yangmin; Lei, Rui; Yang, Xiufang; Yang, Fangzhou published the artcile< Eco-friendly Waterborne Alkyd Resin from Polyethylene Terephthalate Waste>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is waterborne alkyd resin polyethylene terephthalate waste recycling thermomech property.

This work reports a simple and eco-friendly way of recycling polyethylene terephthalate (PET) waste. PET waste was glycolyzed using trimethylolpropane (TMP) giving tetra-functional glycolyzate, to prepare alkyd resin. 0.25% ZnOAc and the TMP to PET molar ratio of 12:1 at 220°C produced the best yield of glycolyzate. The obtained glycolyzate was characterized by Fourier transform IR spectroscopy (FTIR) spectroscopy, 1H and 13C NMR (NMR) and further used in the synthesis of alkyd resins. The properties of the prepared alkyd resins including acid value, the pencil hardness, chem. resistance and thermal stability, were investigated. The pencil hardness of the cured resins film is 3H, which is better than the com. alkyd resin YF-155. Thermogravimetric anal. (TGA) exhibited polymer decomposition occurred above 160°C. When compared to com. coatings, Zanthoxylum bungeanum seed oil (ZSO)-based alkyd resin from postconsumer PET bottles has potential for com. applications, and may even be superior in thermal and chem. resistance.
