Synthesis of amides via Beckmann rearrangement of ketoximes promoted by cyanuric chloride (TCT)/DMSO under mild conditions has been reported. Conditions of the Beckmann rearrangement, e.g., solvents, the ratios of TCT/DMSO, and the temperature, were investigated using diphenylmethanone oxime as a substrate. The optimized conditions were adopted to afford fourteen amides with yields ranging from 20% to 99%. A plausible mechanism involving an active dimethyl alkoxysulfonium intermediate was proposed according to the mass spectrometry analysis. To our best knowledge, this is the first case of study on Beckmann rearrangement of ketoximes promoted by TCT/DMSO under a mild condition to afford amides efficiently. (C) 2020 Elsevier Ltd.

Approximately 60% of human cancers exhibit enhanced activity of ERK1 and ERK2, reflecting their multiple roles in tumor initiation and progression. Acquired drug resistance, especially mechanisms associated with the reactivation of the MAPK (RAF/MEK/ERK) pathway represent a major challenge to current treatments of melanoma and several other cancers. Recently, targeting ERK has evolved as a potentially attractive strategy to overcome this resistance. Herein, we report the design and synthesis of novel series of fused naphthofuro[3,2-c] quinoline-6,7,12-triones 3a-f and pyrano[3,2-c]quinoline-6,7,8,13-tetraones 5a,b and 6, as potential ERK inhibitors. New inhibitors were synthesized and identified by different spectroscopic techniques and X-ray crystallography. They were evaluated for their ability to inhibit ERK1/2 in an in vitro radioactive kinase assay. 3b and 6 inhibited ERK1 with IC50s of 0.5 and 0.19 mu M, and inhibited ERK2 with IC50s of 0.6 and 0.16 mu M respectively. Kinetic mechanism studies revealed that the inhibitors are ATP-competitive inhibitors where 6 inhibited ERK2 with a K-i of 0.09 mu M. Six of the new inhibitors were tested for their in vitro anticancer activity against the NCI-60 panel of tumor cell lines. Compound 3b and 6 were the most potent against most of the human tumor cell lines tested. Moreover, 3b and 6 inhibited the proliferation of the BRAF mutant A375 melanoma cells with IC50s of 3.7 and 0.13 mu M, respectively. In addition, they suppressed anchorage-dependent colony formation. Treatment of the A375 cell line with 3b and 6 inhibited the phosphorylation of ERK substrates p-90RSK and ELK-1 and induced apoptosis in a dose dependent manner. Finally, a molecular docking study showed the potential binding mode of 3b and 6 within the ATP catalytic binding site of ERK2.

Aurone-derived azadienes are well-known four-atom synthons for direct [4 + n] cycloadditions owing to their s-cis conformation as well as the thermodynamically favored aromatization nature of these processes. However, distinct from this common reactivity, herein we report an unusual formal migrative annulation with siloxy alkynes initiated by [2 + 2] cycloaddition. Unexpectedly, this process generates benzofuran-fused nitrogen heterocyclic products with formal substituent migration. This observation is rationalized by less common [2 + 2] cycloaddition followed by 4 pi and 6 pi electrocyclic events. DFT calculations provided support to the proposed mechanism.

SDS of cas: 150-76-5. I found the field of Biochemistry & Molecular Biology; Chemistry; Pharmacology & Pharmacy very interesting.

Cerebral amyloid angiopathy (CAA) commonly found in the aged is pathologically characterized by beta-amyloid (A beta) deposition in the walls of arteries and capillaries of brain. In this study, four flexible multidentate benzyldiamine derivatives as potential probes for cerebrovascular A beta deposition were designed and synthesized. In in vitro inhibition assays, the ligands 18-21 displayed high affinities for A beta aggregates with K-i values of 1.45 +/- 0.53 nM, 1.68 +/- 0.35 nM, 1.16 +/- 0.23 nM and 1.72 +/- 0.19 nM, respectively. A significant improvement in the binding affinity over the monomer, compounds 9-12 or benzyldiamine derivatives, demonstrated the applicability of the multidentate approach. The underlying mechanism of these novel A beta agents was explored by molecular docking technique, which theoretically verified the high affinities of the multidentate benzyldiamine derivatives for A beta aggregates. Moreover, the molecular masses of the ligands 18-21 are more than 700 Dalton, which are believed to be hardly capable of penetrating blood brain barrier. In this regard, these ligands could be used to distinguish CAA from Alzheimer’s disease which is another A beta-related disorder disease. To convert these ligands to positron emission tomography imaging agents, we attempted to radiosynthesize [F-18]18. Though the radiolabeling was not very successful, the preliminary results suggested that these newly proposed multidentate benzyldiamine derivatives may be used as potential A beta imaging agents in cerebral amyloid angiopathy.

Heteroatom-doped carbon materials (HDCMs) with abundant active functional groups and stable structural characteristics are promising catalysts for eco-friendly metal-free catalysis. In this work, phosphorus-doped carbon materials with a highly porous structure and extremely high surface area (>1600 m(2) g(-1)) were successfully prepared via a convenient and scalable strategy using easily available soluble starch and phosphoric acid, which are expected to show good performance in mass-transfer and thus promote the catalytic process. As expected, the as-prepared PC-700 catalyst showed remarkable catalytic performance in aerobic oxidation of benzyl alcohol with a higher TOF value than other previously reported heteroatom-doped carbon catalysts. It also exhibited great tolerance for various substrates, including aromatic, alicyclic, heterocyclic, and aliphatic alcohols. On the basis of the related characterization studies and experimental results, it was proved that the P-O-C species and the defects caused by P-O species doping in the PC-700 catalyst are the active sites for aerobic oxidation. A unique mechanism was proposed for the catalytic process, which is different from that of N-doped graphene and graphene oxide catalyzed reactions that follow a free radical mechanism. In addition, the recycling test and characterization of the reused catalyst indicate that the PC-700 shows extraordinary performance in terms of both recyclability and stability and retains high reactivity even after eight cycles.

Alkaline lignin obtained from paper manufacturing is a potential feedstock for upgrading to produce value-added chemicals. This study demonstrates the efficiencies of synthesized Ni supported CeO2-ZrO2 catalysts to convert this low-cost alkaline lignin into value-added phenolic-based chemicals for further commercial applications. Lignin depolymerization was performed under mild reaction conditions, namely, reaction temperature of 200-300 degrees C, and reaction time of 1-5 h. Three different catalyst preparation methods (simple wet-impregnation, wet-impregnation assisted reduction in H-2 atmosphere and one-step chemical reduction) were investigated and used to evaluate possible correlations between the active Ni phase and catalytic performance in lignin depolymerization. The active Ni phase was successfully formed by one-step chemical reduction method which showed a significant improvement on product yield, especially lignin oil. The best result obtained in lignin depolymerization was by using 10%Ni/CeO2-ZrO2-red catalyst which resulted in producing a high yield of lignin oil (46.8%) from lignin feedstock under mild condition of 250 degrees C. The major phenolic compounds in lignin oil were: guaiacol, methyl-guaiacol, ethyl-guaiacol, vanillin, acetovanillone, and homovanillic acid. Furthermore, the reaction temperature affected the product yield and product distribution resulting in higher diversity of phenolic compounds in lignin oil.

A versatile Rh(i)-catalyzed C6-selective decarbonylative C-H alkenylation of 2-pyridones with readily available, and inexpensive alkenyl carboxylic acids has been developed. This directed dehydrogenative cross-coupling reaction affords 6-alkenylated 2-pyridones that would otherwise be difficult to access using conventional C-H functionalization protocols. The reaction occurs with high efficiency and is tolerant of a broad range of functional groups. A wide scope of alkenyl carboxylic acids, including challenging conjugated polyene carboxylic acids, are amenable to this transformation and no addition of external oxidant is required. Mechanistic studies revealed that (1) Boc(2)O acts as the activator for the in situ transformation of the carboxylic acids into anhydrides before oxidative addition by the Rh catalyst, (2) a decarbonylation step is involved in the catalytic cycle, and (3) the C-H bond cleavage is likely the turnover-limiting step.

A series of highly CO2-soluble open-chain crown ether bridged diphosphates were designed and prepared as chelating ligands which were used to extract lanthanide ions from cellulose paper into supercritical CO2 (ScCO2). These ligands were designed by introducing different ester side chains and joining the two phosphorus groups with different length of ethylene oxide group which could provide enhanced solubility and complexation ability. The solubility data of these synthesized diphosophates in ScCO2 were measured at 313.15 K and 10.65 MPa-13.69 MPa. Lanthanides metal ions including La3+, Ce3+, Pr3+, Nd3+, Sm3+, Gd3+, Er3+, and Yb3+ were successfully removed from the solid matrix by supercritical fluid extractions using these chelating ligands at 313.15 K and 20 MPa. The extraction efficiency of metal ion was affected by chelating ligands’ side chain, which increased from 68% to 94% mainly driven by the increased solubility capability.

Herein, a light-driven, atom-economical process that provides access to enantiomerically enriched substituted chiral 1-pyrroline derivatives is introduced. The strategy involves the distal functionalization of acyl heterocycles through a hydrogen-atom transfer (HAT) process and the use of tailor-made ketimines as reliable electrophilic partners. This transformation is translated into an enantiomerically controlled radical/polar cascade reaction in which water is produced as the sole by-product and stereoselectivity is dictated by coordination to a chiral-at-rhodium catalyst.
