This work entails deep red emitting Eu-III based complexes with a variety of ternary beta-diketonate ligands and 1,10-phenanthroline as the ancillary ligand in the system. The solid state structure and spectroscopic analysis has been outlaid in terms of photoluminescence and crystallography. A luminescence quantum efficiency of 50% was obtained for the [tris-(4,4,4-trifluoro-1-chlorophenyl-butanedione)mono-(1,10-phenanthroline)europium(iii)] complexes. Moreover, complexes [tris-(2,2,6,6-tetramethyl-heptanedione)mono-(1,10-phenanthroline) europium(iii)] and {[hexa-(benzyl carboxylic acid) bis-(1,10-phenanthroline)di-europium(iii)]-mu-[kappa(2)-O,O ‘-(benzyl carboxylic acid)](2)} were found to also have quantum yields of 9% and 28% with respective sensitization efficiencies of 85%, 15% and 58%. These results were articulated with crystallographic details pertaining to the nature of coordination and the effect of steric and electronic properties thereof which somewhat impacts the Eu-N bond distances. A symmetry correlation was drawn between the crystallographic data and the photoluminescence data.

An air-stable mu-oxo-bridged binuclear Lewis acid of titanium(IV) salophen perfluorobutanesulfonate [{Ti(salophen)H2O)(2)O][OSO2C4F9](2) (1) was successfully synthesized by the reaction of Ti-IV(salophen)Cl-2 with AgOSO2C4F9 and characterized by techniques such as IR, NMR and HRMS. This complex was stable open to air over a year, and exhibited good thermal stability and high solubility in polar organic solvents. The complex also had relatively strong acidity with a strength of 0.8 < Ho <= 3.3, and showed high catalytic efficiency towards various C-S and C-Se bond formations in the presence of zinc power. This catalytic system affords a mild and efficient approach to synthesis of thio- and selenoesters, alpha-arylthio- and seleno-carbonyl compounds, and thio- and selenoethers. (C) 2019 Elsevier Ltd.

We synthesized N-benzoyl-protected peptide nucleic acid (PNA) monomers, which are robust under the conditions for deprotecting the 9-fluorenylmethoxycarbonyl (Fmoc) group by piperidine but are removable by aqueous ammonia and hence totally compatible with Fmoc-solid phase synthesis. This new invention expands the range of available nucleobase sequences, allowing us to use acid-sensitive PNA oligomers and purine nucleotides (both of which are difficult to use in the conventional methods) in the preparation of PNA-DNA chimeras to avoid the drawbacks of traditional PNAs.

Novel benzo[d] thiazole-based analogues were synthesized with the aim of screening their in vitro anticancer activity. All the new derivatives 4-21 were evaluated against human hepatocellular carcinoma (HepG-2) and breast cancer cells (MCF-7) using doxorubicin as a reference drug. All compounds exhibited excellent potency against MCF-7 (IC50 values ranging from 0.71 +/- 0.4 to 1.04 +/- 0.7 mu M) and variable promising potency against HepG-2 (IC50 ranged from 2.53 +/- 2.5 to 3.47 +/- 3.4 mu M) comparing with the standard (IC50 = 1.03 +/- 0.8 mu M and 2.85 +/- 1.9 mu M, respectively) in addition to their safety towards the normal cell line. Compounds 5, 6, 7, 13 and 16 having the highest cytotoxic activity, were further evaluated for their EGFR inhibitory activity using Erlotinib as a reference drug. Molecular docking studies were performed for the promising compounds 5, 6 and 7 to interpret their detected enzymatic activities based upon their binding interactions with the receptor. Moreover, cell cycle analysis and detection of apoptosis induction illustrated that compounds 5 and 6 exhibited a significant pre G(1) and G(2)/M cell cycle arrest, in comparison with the untreated MCF-7 cells. In addition, compounds 5 and 6 elevated the levels of the oncogenic parameters; Bax, p53 and caspase-3 with decreased level of Bcl-2. These previous encouraging results of biological evaluation of the newly synthesized benzothiazoles could recommend an excellent framework toward the detection of new potent antitumor leads.

Methods for selective C-H bond functionalization have provided chemists with versatile and powerful toolboxes for synthesis, such as the late-stage modification of a lead compound without the need for lengthy de novo synthesis(1-5). Cleavage of an sp(3) C-H bond via hydrogen atom transfer (HAT) is particularly useful, given the large number of available HAT acceptors and the diversity of reaction pathways available to the resulting radical intermediate(6-17). Site-selectivity, however, remains a formidable challenge, especially among sp(3) C-H bonds with comparable properties. If the intermediate radical could be further trapped enantioselectively, this should enable highly site- and enantioselective functionalization of C-H bonds. Here we report a copper (Cu)-catalysed site- and enantioselective allylic C-H cyanation of complex alkenes, in which a Cu(ii)-bound nitrogen (N)-centred radical plays the key role in achieving precise site-specific HAT. This method is shown to be effective for a diverse collection of alkene-containing molecules, including sterically demanding structures and complex natural products and pharmaceuticals.

Trace volatile organic compounds (VOCs) such as aldehydes and aromatics significantly deteriorate the indoor air quality especially in newly-decorated buildings. The universal water vapor would greatly decrease the adsorption capacity of ad-sorbents for trace VOCs via competitive adsorption and capillary condensation. Herein, we developed a strategy to subsequently modify the internal and external surface of CAU-1, an aluminum-based metal-organic framework (MOF), to significantly improve its humidity resistance. First, anhydrides were used to transfer amino groups of CAU-1 into hydrophobic groups via amide reaction. Second, polydimethylsiloxane was used to form a hydorphobic coating on its external surface. The adsorption capacity of as-modified CAU-1 for 1 ppm toluene increased about 6 times under 50% relative humidity (RH) at 298 K, even much higher than those of common adsorbents including hydrophobic ZSM-5. In addition, it could be completely regenerated below 373 K, about 65 K lower than that required for regenerating ZSM-5 under the same condition, which not only greatly reduces the energy consumption but also improves the safety and feasibility of in-situ regeneration of adsorbents in indoor environment.

Axially chiral phenols are attractive targets in organic synthesis. This motif is central to many natural products and widely used as precursors to, or directly, as chiral ligands and catalysts. Despite their utility few simple catalytic methods are available for their synthesis in high enantiopurity. Herein the atropselective acylation of a range of symmetric biaryl diols is investigated using isothiourea catalysis. Studies on a model biaryl diol substrate shows that the high product er observed in the process is a result of two successive enantioselective reactions consisting of an initial enantioselective desymmetrization coupled with a second chiroablative kinetic resolution. Extension of this process to a range of substrates, including a challenging tetraorthosubstituted biaryl diol, led to highly enantioenriched products (14 examples, up to 98:2 er), with either HyperB(TM) or B-TM identified as the optimal catalyst depending upon the substitution pattern within the substrate. Computation has been used to understand the factors that lead to high enantiocontrol in this process, with maintenance of planarity to maximize a 1,5-S…O interaction within the key acyl ammonium intermediate identified as the major feature that determines atropselective acylation and thus product enantioselectivity.

Axially chiral atropisomeric compounds are widely applied in asymmetric catalysis and medicinal chemistry, and efficient methods for their synthesis are in high demand. This applies in particular to atropisomers derived from five-membered aromatic rings because their lower barrier for rotation among the biaryl axis limits their asymmetric synthesis. We report here an enantioselective C-H functionalization method using our chiral RhJasCp complex for the synthesis of the biaryl atropisomer types that can be accessed from three different five-membered-ring heterocycles.

The microporous framework copper silicates CuSH-1NaK (1) and SGU-29 (2) – prepared using hydrothermal conditions – are effective heterogeneous oxidation catalysts for producing benzaldehyde (BzAld) and benzoic acid (BzAcid) from benzyl alcohol (BzOH), under mild reaction conditions (approximately atmospheric pressure, 70 degrees C). The copper silicate heterogeneous catalysts triggered a radical reaction mechanism leading to the target products; in particular, BzAcid was formed in up to 94 % yield and 100 % selectivity from BzAld. The type of oxidant and solvent influenced the catalytic performances.

An electrochemical synthesis method for the selective N1-acylation of indazoles has been developed. This anion pool approach electrochemically reduces indazole molecules generating indazole anions and H-2. Acid anhydrides are then introduced to the solution resulting in selective acylation of the N1-position of the indazoles. This procedure can also be applied to the acylation of benzimidazoles and indoles. The reaction can also be performed using a 9 V battery without loss of reaction efficiency.
