Low-Pressure Cobalt-Catalyzed Enantioselective Hydrovinylation of Vinylarenes

An efficient and practical protocol for the enantioselective cobalt-catalyzed hydrovinylation of vinylarenes with ethylene at low (1.2 bar) pressure has been developed. As precatalysts, stable [L2CoCl2] complexes are employed that are activated in situ with Et2AlCl. A modular chiral TADDOL-derived phosphine-phosphite ligand was identified that allows the conversion of a broad spectrum of substrates, including heterocyclic vinylarenes and vinylferrocene, to smoothly afford the branched products with up to 99 % ee and virtually complete regioselectivity. Even polar functional groups, such as OH, NH2, CN, and CO2R, are tolerated.

Formation of alkoxy groups in the synthesis of butylated urea formaldehyde resins: Reaction mechanism and kinetic model

Water-resistant amino resins have found diverse applications in the paint and coatings industry. Butylated urea formaldehyde (BUF) amino resins exhibit excellent water-resistant properties due to the presence of butyl groups in its molecular structure. BUF resins are typically synthesized in two steps via addition and condensation reactions. Here, we develop detailed reaction mechanism for the BUF synthesis and develop the kinetic model for the addition reactions. The species in the mechanism are represented in a generic fashion and thus, our mechanism can be utilized not only for the BUF condensation reactions but also for the synthesis of other amino resins. The mechanism incorporates species containing, ?CH2?O?CH2? linkages and the new ?CH2?O?C4H9 end group, the presence of which have been confirmed experimentally. Further, the kinetic model for the addition reactions is developed and the values of the rate constants are determined from the isothermal experiments conducted at different temperatures. We demonstrate that the predictions from our kinetic model match the experimental observations for reaction synthesis under non-isothermal conditions. In addition, we also predict the transient behavior of intermediate species including ?CH2?O?CH2? linkages and ?CH2?O?C4H9 end groups, which qualitatively matches our experimental findings. The presence of these linkages opens up new possibilities to design resin-based composite materials, where functionality of oxygen can be utilized to graft nanomaterials onto the oligomers in subsequent steps. Our mechanism and the kinetic model can also be utilized for the optimization of the process conditions required for synthesis of resin with tailor-made properties.

Palladium-Catalyzed Tandem Synthesis of 2-Trifluoromethylthio(seleno)-Substituted Benzofused Heterocycles

The tandem synthesis of 2-trifluoromethylthio(seleno)-substituted benzofurans using palladium-catalyzed conditions is reported. Trifluoromethylthio(seleno)lation of 2-(2,2-dibromovinyl)phenols with (bpy)CuSCF3 or [(bpy)CuSeCF3]2 furnishes several 2-trifluoromethylthio(seleno)lated benzofurans in acceptable to good yield. Mechanistic investigations were performed to elucidate the reaction pathway, which was involved in the formation of a 2-bromobenzofuran species. The scope of this protocol was further extended to the preparation of 2-trifluoromethylthio(seleno)lated benzothiophenes and indoles.

Chemical inactivation of the E3 ubiquitin ligase cereblon by pomalidomidebased homo-PROTACs

The immunomodulatory drugs (IMiDs) thalidomide and its analogs, lenalidomide and pomalidomide, all FDA approved drugs for the treatment of multiple myeloma, induce ubiquitination and degradation of the lymphoid transcription factors Ikaros (IKZF1) and Aiolos (IKZF3) via the cereblon (CRBN) E3 ubiquitin ligase for proteasomal degradation. IMiDs have recently been utilized for the generation of bifunctional proteolysis targeting chimeras (PROTACs) to target other proteins for ubiquitination and proteasomal degradation by the CRBN E3 ligase. We designed and synthesized pomalidomide-based homobifunctional PROTACs and analyzed their ability to induce self-directed ubiquitination and degradation of CRBN. Here, CRBN serves as both, the E3 ubiquitin ligase and the target at the same time. The homo-PROTAC compound 8 degrades CRBN with a high potency with only minimal remaining effects on IKZF1 and IKZF3. CRBN inactivation by compound 8 had no effect on cell viability and proliferation of different multiple myeloma cell lines. This homo-PROTAC abrogates the effects of IMiDs in multiple myeloma cells. Therefore, our homodimeric pomalidomide-based compounds may help to identify CRBN?s endogenous substrates and physiological functions and investigate the molecular mechanism of IMiDs.

Simultaneous determination of multi-class pesticide metabolites in fish (Siluriformes: Ariidae): protocol developed for human dietary risk in Ceara coast, Brazil

An analytical protocol for the determination of multi-class pesticide metabolites chlorpyrifos-methyl (Chlorp-M), S-metolachlor (S-Metola), malaoxon (malaox), 2-chloro-4,6-diamino-1,3,5-triazine (2-CAAT), carbofuran phenol (CarbPhenol), 3-phenoxybenzoic acid (3-PBA) and one polycyclic aromatic hydrocarbon metabolite 1-hydroxypyrene (1-OHP) in fish was developed using the analytical technique GC?MS. Besides the verification of metabolite occurrence in catfish from both metropolitan region and intensive farming region, the protocol was applied to evaluate human health risk due to the contaminated fish consumption in Brazilian tropical semiarid coast, for the first time. Following the national and international quality standards, the analytical protocol showed acceptable recoveries with good repeatability. Limit of detection (LD) and limit of quantification (LQ) values ranged from 0.15?mug L?1 to 36.0?mug L?1 and from 0.55?mug L?1 to 112.9?mug L?1, respectively, and the sensitivity was considered satisfactory since it is a complex matrix. Only tree pesticide metabolites were detected in the captured catfish. CarbPhenol and 3-PBA presence may be attributed to the application in rural and urban activities for pest control, public health campaigns and household, while malaox presence may be due to the dengue control program. Malaox contents were significantly higher than 3-PBA and CarbPhenol for the three estuaries of the Ceara coast, but the dietary risk due to the consumption of these fish, mainly for the coastal communities, based on the values established for their parental compounds, was considered low for both 3-PBA and malaox, and of probable high risk for CarbPhenol. Results represent an alert to the high possibility of risks to human health due to the overuse of pesticides in Brazil, mainly carbofuran pesticide.
