Hydrothermal treatment of gadolinium nitrate and 2,6-naphthalenedicarboxylic acid (H2NDC) afforded a new metal-organic framework compound, {[Gd-4(NDC)(6)(H2O)(6)]center dot 2H(2)O}n(1). Compound 1 has been characterized by single-crystal X-ray crystallography, elemental analysis, FT-IR spectroscopy, therrmogravimetric analysis (TGA) and powder X-ray diffraction analysis. It is crystallized in the monoclinic system with the P2(1)/n space group. Four crystallographically distinct Gd (III) centres are interconnected with each other through bridged carboxylato oxygen atoms and water molecules to form tetranuclear secondary building units, which are further connected through the carboxylato ligand and the network propagates along the crystallographic ac plane to form a 2D structure. Subsequent reinforcement from the remaining carboxylato oxygen atoms gives rise to a robust 3D framework structure. Thermogravimetric analysis demonstrates that compound 1 is fairly stable after dehydration under a nitrogen atmosphere. Notably, compound 1 is capable of catalyzing the O-arylation reaction efficiently between substituted phenols and bromoarene under heterogeneous conditions at 80 degrees C to afford unsymmetrical diarylethers.

A novel series of 2-arylbenzothiazoles 9, 10, and 12 were designed and synthesized as VEGFR-2/FGFR-1/PDGFR-beta multiangiokinase inhibitors targeting breast cancer. Structural elongation of the known 2-phenylbenzothiazole scaffold (type I protein kinase inhibitor [PKI]), was carried out to afford series of type II PKIs 9, 10, and 12. Compounds 9d, 9f, 9i, and 9k exhibited potent multikinase inhibitory activity with IC50 values of 0.19, 0.18, 0.17, and 0.13 mu M, respectively, against VEGFR-2; IC50 values of 0.28, 0.37, 0.19, and 0.27 mu M, respectively, against FGFR-1; and IC50 values of 0.07, 0.04, 0.08, and 0.14 mu M, respectively, against PDGFR-beta. Moreover, the synthesized benzothiazoles demonstrated promising cytotoxic activity against the MCF-7 cell line. The most potent benzothiazoles 9d and 9i exhibited IC50 values of 7.83 and 6.58 mu M, respectively, on the MCF-7 cell line in comparison to sorafenib (III), which showed IC50 = 4.33 mu M. Additionally, 9d and 9i showed VEGFR-2 inhibitory activity in MCF-7 cells of 81% and 83% when compared with sorafenib (III), which showed 88% inhibition. Molecular docking of the designed compounds in the VEGFR-2 and FGFR-1 active sites showed the accommodation of the 2-phenylbenzothiazole moiety, as reported, in the hinge region of the receptor tyrosine kinase (RTK)-binding site, while the amide moiety is involved in hydrogen bond interactions with the key amino acids in the gate area; this in turn directs the aryl group to the hydrophobic allosteric back pocket of the RTKs in a type II-like binding mode. The synthesized benzothiazoles showed satisfactory ADME properties for further optimization in drug discovery.

In the present work, a new type of bio-based benzoxazines were prepared by using aniline, N, N-dimethyl amino propyl amine (DMAPA) and caprolactam modified DMAPA with eugenol. The benzoxazines resulted were characterized for their molecular structure by Fourier transform infrared and nuclear magnetic resonance spectroscopy. The polymerization process of benzoxazines and their thermal behavior were studied by differential scanning calorimetry and thermogravimetric analysis, respectively. Moreover, the effect of chemical blending of the synthesized benzoxazines with conventional benzoxazines [bisphenol A benzoxazine (BPAb) and bisphenol F benzoxazine (BPFb)] and bismaleimide was studied to bring down the polymerization temperature by creating supplementary potential sites for polymerization. Furthermore, to reduce the polymerization temperature, the benzoxazines synthesized in the present study were partially incorporated with 10 wt % of catalysts (4-hydroxy phenylmaleimide, 4-amino phenol, and 4-hydroxy acetophenone). The graphene reinforced polybenzoxazine composites were also prepared by incorporating varying weight percentages (1, 3, 5, 7, and 10 wt %) of graphene oxide to obtain hybrid nanocomposites. From the results obtained, it was observed that the polymerization temperature (T-p) was significantly reduced (more than 31 degrees C) in both the cases of blends of conventional BPAb and BPFb. It was also observed that the values of the dielectric constant of graphene reinforced hybrid composites are significantly enhanced. (c) 2018 Wiley Periodicals, Inc. J. Appl. Polym.

A series of iminophosphorane-thiourea/urea bifunctional catalysts was synthesized and utilized for the isoselective ring-opening polymerization of rac-lactide. The ROPs were promoted efficiently, affording the polylactides with controlled molecular weight, narrow molecular weight distribution and well-defined end groups without undesired side reactions. The experiment data revealed that ROPs of rac-LA are a controlled/living process. The highest stereoselectivity (P-m) was up to 0.80 using rac-IPU-1 under mild reaction conditions. The mechanistic study indicated that stereoselective ROPs of rac-LA were mainly controlled by a chain-end control mechanism when using rac/(R,R)-IPTU-1/IPU-1 as catalysts. Additionally, the ee values of -11% at 0 degrees C and -17% at -40 degrees C were achieved at about 50% conversion using (S)-IPU-2 as a chiral catalyst. The selectivity factor (s = k(L)/k(D)) of 1.6 indicated that a clear kinetic resolution occurred and the enantiomorphic site control mechanism was involved.

A vast range of novel TADDOL-based diphosphite ligands were first synthesized and applied in the nickel-catalyzed asymmetric hydrocyanation of disubstituted methylenecyclopropanes. By employing these new catalysts, the conversion of diverse methylenecyclopropanes into their corresponding allylic nitriles was first enabled, in good yield with excellent enantioselectivities.

A mild general method for difluoromethylthiolation of aldehydes with PhSO2SCF2H and a decatungstate photocatalyst under redox-neutral conditions has been developed. This reaction is highly efficient, scalable, and oxidant-free. The broad substrate scope and excellent functional group tolerance of the reaction make it suitable for generating libraries of difluoromethyl thioesters. We demonstrated the utility and sustainability of the method by synthesizing several structurally complex difluoromethyl thioesters.

The palladium-catalyzed benzylic-like nucleophilic substitution of benzofuran-2-ylmethyl acetate with N, S, O and C soft nucleophiles has been investigated. The success of the reaction is dramatically influenced by the choice of catalytic system: with nitrogen based nucleophiles the reaction works well with Pd-2(dba)(3)/dppf, while with sulfur, oxygen and carbo-nucleophiles [Pd(eta(3)-C3H5)Cl](2)/XPhos is more efficient. The regiochemical outcome shows that the nucleophilic substitution occurs only on the benzylic position of the eta(3)-(benzofuryl)methyl complex. The high to excellent yields and the simplicity of the experimental procedure make this protocol a versatile synthetic tool for the preparation of 2-substituted benzo[b]furans.

Hydrolytic cleavage of C-O bond was systematically studied in acidic/alkaline aqueous solution. For phenethoxybenzene (PEB) hydrolysis, 2-phenylethanol and phenol were formed as main products in AlCl3 solutions, whereas styrene was preferred with Na2CO3. After a quantitative evaluation of the kinetics of elementary steps, it was concluded that both AlCl3 and Na2CO3 promoted protons assisted C-O bond scission in H2O, whereas alkaline enhanced the dehydration of produced 2-phenylethanol. Kinetic and isotope labeling experiments demonstrated that the hydrolytic rates of PEB were first order with respect to substrate concentrations, hydrolytic cleavage of C-O bond was rate-determining step. The study shed light on the promotional effects and hydrolytic mechanism over acid/base-catalyzed lignin depolymerization in water.
