This communication describes the palladium-catalyzed reductive carbonylation of aryl fluorosulfonates (ArOSO2F) using syngas as an inexpensive and sustainable source of carbon monoxide and hydrogen. The conversion of phenols to aryl fluorosulfonates can be conveniently achieved by employing the inexpensive commodity chemical sulfuryl fluoride (SO2F2) and base. The developed continuous flow formylation protocol requires relatively low loadings for palladium acetate (1.25 mol%) and ligand (2.5 mol%). Good to excellent yields of aryl aldehydes were obtained within 45 min for substrates containing electron withdrawing substituents, and 2 h for substrates containing electron donating substituents. The optimal reaction conditions were identified as 120 degrees C temperature and 20 bar pressure in dimethyl sulfoxide (DMSO) as solvent. DMSO was crucial in suppressing Pd black formation and enhancing reaction rate and selectivity.

The catalyst system trans-Ru(H)(2)(1R,2R)-N,N-bis{2-[bis (3,-dimethylphenyl)phosphino]benzyl}cyclohexane-1,2-diamine, NaOEt, in DME or THF solvent hydrogenates a series of functionalized racemic esters under mild conditions with dynamic kinetic resolution with up to 100% conversion, 95% enantiomeric excess, and 1000 turnovers. A preliminary mechanistic study reveals that several exchange and scrambling processes occur during the hydrogenation.

The increasing pharmaceutical importance of trifluoromethylarenes has stimulated the development of more efficient trifluoromethylation reactions. Tremendous efforts have focused on copper- and palladium-mediated/catalyzed trifluoromethylation of aryl halides. In contrast, no general method exists for the conversion of widely available inert electrophiles, such as phenol derivatives, into the corresponding trifluoromethylated arenes. Reported herein is a practical nickel-mediated trifluoromethylation of phenol derivatives with readily available trimethyl(trifluoromethyl)silane (TMSCF3). The strategy relies on PMe3-promoted oxidative addition and transmetalation, and CCl3CN-induced reductive elimination. The broad utility of this transformation has been demonstrated through the direct incorporation of trifluoromethyl into aromatic and heteroaromatic systems, including biorelevant compounds.

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.

A direct catalytic asymmetric addition of acetonitrile to aldehydes that realizes over 90 % ee is the ultimate challenge in alkylnitrile addition chemistry. Herein, we report achieving high enantioselectivity by the strategic use of a sterically demanding Ni-II pincer carbene complex, which afforded highly enantioenriched beta-hydroxynitriles. This highly atom-economical process paves the way for exploiting inexpensive acetonitrile as a promising C2 building block in a practical synthetic toolbox for asymmetric catalysis.

A series of fourteen novel thiazolidine-2,4-dione derivatives clubbed with pyrazole moiety were synthesized via four step reaction procedure. Reactions were monitored by thin layer chromatography and were characterized by physicochemical and spectrophotometric (IR, Mass, (HNMR)-H-1 and (CNMR)-C-13) analysis. The spectral data were in good agreement with their structures. The title compounds were docked against peroxisome proliferated activated receptors (PPAR-gamma) and alpha-amylase and further evaluated for in vivo and in vitro antidiabetic, in vitro anti-inflammatory and antioxidant activities. Compound GB14 exhibited significant blood glucose lowering activity and was also found to be active inhibitor of alpha-amylase. Compound GB7 was found to be potent anti-inflammatory agent in terms of reducing inflammatory markers (TNF-alpha, IL-beta, MDA) and also showed antioxidant activity to good extent. Therefore, these compounds may be considered as promising candidates for the development of new antidiabetic agents.

Fe3O4@SiO2@(CH2)(3)-urea-quinoline sulfonic acid chloride, as a novel and efficient nanomagnetic catalyst bearing urea linkers, was designed, synthesized and then fully characterized by using various techniques. To investigate the catalytic activity of the described catalyst, it was used for the synthesis of coumarin containing 1,4-dihydropyridines (DHPs), through a condensation reaction of aromatic aldehydes, 4-hydroxycoumarin, and ammonium acetate under solvent-free conditions. This procedure includes important aspects like simple procedure, simplicity of product isolation using water, decreasing the temperature of reaction, disuse of solvent, high to excellent yields, environmentally benign reaction conditions and short reaction times. Also, the presented catalyst was recycled and reused for at least five times with only a negligible decrease in its catalytic activity. The applied catalyst has both acidic and H-bond donor-acceptor sites so that it can use as a dual role catalytic system. (C) 2020 Elsevier B.V. All rights reserved.

Despite common perception, the use of strong bases in Wittig chemistry is utterly unnecessary: we report a series of novel ion-pair phosphonium carboxylate reagents which are essentially storable ylides. These reagents are straightforwardly prepared in excellent yields, and their fluxional nature permits clean olefination of a broad range of aldehydes and even hemiacetals.

Useful fuels and chemicals can be produced from lignin by microwave-assisted pyrolysis, but a dearth of understanding of this process impedes its successful implementation. Continuous mass loss kinetics of the pyrolysis of Kraft lignin pellets were carried out in an innovative reactor system comprised of a high-Q cylindrical microwave resonant cavity and a specially designed quartz reactor, in the temperature range of 300-700 ?C. Multiphysics numerical simulations indicated that both absorbed power and resulting temperatures profiles are heavily dependent on position of the sample relative to the electric field. Kraft lignin degradation (5 g samples) was complete in about 40 s, which was much faster than conventionally heated reactors. Activation energies (5-22 kJ/mol) and pre-exponential factors (0.06-0.64 s-1) were indicative that the process is low in energy consumption. At higher temperatures, phenols and phenolics were the major constituents of the bio-oil. A reliable method of obtaining microwave-assisted mass loss kinetics continuously is established.
