Three hydroxymethyl bridged Cu(ii) complexes of a pyridoxal Schiff base ligand 4-((E)-(2-(pyridin-2-yl)ethylimino)methyl)-5-(hydroxymethyl)-2-methylpyridin-3-ol (LH) have been synthesized and characterized on the basis of spectroscopic, elctrochemical and structural properties. The X-ray crystal structures of the complexes reveal dual denticity of the ligand, bidenticity in the absence of a co-ligand as in complex1, and tridenticity in the presence of a co-ligand such as SCN-/N(CN)(2)(-)as in complexes2and3. The complexes, though binuclear in the solid state, exist as a monomeric unit in solution due to the exceptionally long axial Cu-O-hydroxymethyl(2.4-2.5 angstrom) bond. All three complexes show efficient catalytic activities towards the aerial oxidation of 3,5-ditertiarybutylcatechol (DTBCH2) withk(cat)values of 5.38 x 10(4)h(-1), 1.18 x 10(5)h(-1)and 1.06 x 10(5)h(-1)in methanol. Complexes1and2also act as a selective sulphide ion sensor withK(b)values of 6.6 x 10(3)M(-1)and 8.1 x 10(3)M(-1), respectively, while their respective L.O.D. values are 3.4 mu M and 3.2 mu M.

A 1,10-phenanthroline based polymer named PPPhen(i.e., polymer from pyrene 1,10-phenanthrolin) was prepared by the Friedel-Crafts reaction of 1,10-phenanthroline and pyrene cross-linked with dimethoxymethane. The related Pd catalyst Pd@PPPhen was prepared by supporting Pd nanoparticles(NPs) on the PPPhen material. PPPhen and Pd@PPPhen were characterized by means of scanning electron microscopy(SEM), transmission electron microscopy, N-2 adsorption-desorption, Fourier-transform infrared and X-ray photoelectron spectroscopy analyses. The results showed that PPPhen polymer was highly porous and that the phenanthroline group can enhance the stability of the Pd nanoparticles. Pd@PPPhen also exhibited good catalytic activity in the aerobic oxidation of alcohols to aldehydes and ketones, and Pd@PPPhen was recyclable with durable activity and retentive structures.

The reactivity of bidentate Au-III-Cl species, [(C<^>N)AuCl2], with a bisphosphine or carbon donor ligands results in reductive elimination. Combined experimental and computational investigations lead to the first evidence of a direct intramolecular C(sp(2))-N(sp(2)) bond formation from a monomeric [(C<^>N)AuCl2] gold(iii) complex. We show that bidentate ligated Au(iii) systems bypass transmetallation to form C(sp(2))-N(sp(2)) species and NHC-Au-Cl. Mechanistic investigations of the reported transformation reveal a ligand-induced reductive elimination via a key Au-III intermediate. Kinetic studies of the reaction support a second-order rate process.

Herein we report, a mononuclear, highly fluorescent zinc(ii) complex Zn(L)(N-3)(H2O) (1) that was prepared by an easy one pot method, in which the tridentate Schiff base ligand (E)-4-((2-(dimethylamino)ethylimino)methyl)-5-(hydroxymethyl)-2-methylpyridin-3-ol (HL) was generated in situ. The compound is characterized by various spectroscopic techniques, and its structure was determined by single crystal X-ray diffraction studies. DFT calculations were used to understand the electronic structures of the ligand and the complex, and TD-DFT calculations were performed to interpret the nature of the electronic transitions observed in their UV-vis spectra. In the complex, Zn(II) is found to be penta-coordinated with one azide ligand, an aqua ligand and a monoanionic tridentate N,N,O-donor ligand. In an aqueous methanol (1:9 by volume) solution, at the physiological pH (0.01 M Tris-HCl buffer, pH 7.4), compound 1 exhibits an intense greenish blue fluorescence (lambda(ex) 390 nm, lambda(em) 462 nm), whose intensity is about 17-fold stronger than that of the free ligand. Compound 1 is found to show significant DNA binding activity. The pyridoxal appended tridentate ligand can be used for the bio-imaging of Zn(II).

An efficient, reusable and stable binaphthyl stabilized Pd-nanoparticles (Pd-BNP) catalyzed the direct ortho-C-H hydroxylation of acetophenone oxime ethers under neutral and phosphine ligand-free condition has been developed. A readily available, economic, safe and greener oxidant oxone has been used in this direct ortho-hydroxylation. The scope of the reaction has been studied with various acetophenone oxime ethers including electron rich to electron deficient system and the reaction afforded only mono hydroxylated products in a highly regioselective manner. Several control experiment results confirmed that the oxone is the hydroxyl source. The Pd-BNP catalyst has been reused up to five times. The heterogeneous test confirmed that the reaction is catalyzed by the heterogeneous Pd-BNP catalyst.

Koji amazake, prepared from rice koji, is a traditional Japanese sweet beverage. The main source of sweetness is glucose derived from rice starch following digestion by enzymes of Aspergillus oryzae during saccharification. The temperature of this process was empirically determined as 45 degrees C-60 degrees C, but no studies have systematically investigated the effect of temperature on saccharification efficiency. We addressed this in the present study by evaluating saccharification efficiency at various temperatures. We found that glucose content was the highest at 50 degrees C (100%) and was reduced at temperatures of 40 degrees C (66.4%), 60 degrees C (91.9%), and 70 degrees C (76.6%). We previously reported that 12 types of oligosaccharides are present in koji amazake; the levels of eight of these, namely nigerose, kojibiose, trehalose, isomaltose, gentiobiose, raffinose, panose, and isomaltotriose, were the highest at 50 degrees C-60 degrees C, whereas sophorose production was maximal at 70 degrees C. Based on these findings, we initially performed saccharification at 50 degrees C and then switched the temperature to 70 degrees C. The maximum amount of each saccharide including sophorose that was produced was close to the values obtained at these two temperatures. Thus, oligosaccharide composition of koji amazake is dependent on saccharification temperature. These findings provide useful information for improving the consumer appeal of koji amazake by enhancing oligosaccharide content. (C) 2018, The Society for Biotechnology, Japan. All rights reserved.

Synthesis of 2,6-disubstituted pyridines from pyridotriazoles through palladium-catalyzed aerobic oxidative denitrogenative reactions has been described. Denitrogenation of arylated pyridotriazoles generates metal-carbene intermediates in situ and provides selectively 6-aryl-2-benzoylpyridines. The same conditions have been extended to regioselective C-3 and C-8 diarylation of several imidazo[1,2-a]pyridines.

4-Hydroxymethyl-2-hetaryl(hetaroyl)furo[2,3-c]pyridines, the products of furan cyclization of pyridoxal with acylmethyl- and heteroarylmethyl halides, easily react with thionyl chloride in DMF to form new series of 4-chloromethyl-2-heteroaryl[2,3-c]pyridines. Further action of primary or secondary amines on these chloromethyl derivatives leads to the nucleophilic substitution of chlorine atoms with the formation of 4-aminomethyl-2-heteroaryl[2,3-c]pyridines. The study of anti-infective activity of the 4-RCH2-furo[2,3-c]pyridines (R = OH, Cl, (NRR2)-R-1) showed significant protistocidal and moderate antibacterial activity of some of representatives of these compounds.

Herein, the development of a visible-light-induced catalytic system to achieve the decarboxylative acylation of pyridine N-oxides with alpha-oxocarboxylic acids, at room temperature and using the organic dye fluorescein dimethylammonium as a new type of photocatalyst, is reported. A series of 2-arylacylpyridine N-oxides were selectively synthesized in moderate to good yields by controlling the polarity of the reaction solvent. The developed strategy was successfully applied in the synthesis of an important intermediate of the drug, acrivastine, on a gram scale. Notably, this is the first time that fluorescein dimethylammonium has been used to catalyze the Minisci-type C-H decarboxylative acylation reaction. The mechanism of decarboxylative acylation was studied by capturing adducts of acyl radicals and 1,1-diphenylethylene to confirm a radical mechanism. The disclosed catalytic system provides a green synthetic strategy for decarboxylative acylation without the use of additional oxidants or metal catalysts.
