A series of 1,3-indandione-terminated pi-conjugated quinoids were synthesized by alkoxide-mediated rearrangement reaction of the respective alkene precursors, followed by air oxidation. This new protocol allows access to quinoidal compounds with variable termini and cores. The resulting quinoids all show LUMO levels below -4.0 eV and molar extinction coefficients above 10(5) L mol(-1) cm(-1). The optoelectronic properties of these compounds can be regulated by tuning the central cores as well as the aryl termini ascribed to the delocalized frontier molecular orbitals over the entire molecular skeleton involving aryl termini. n-Channel organic thin-film transistors with electron mobility of up to 0.38 cm(2) V-1 s(-1) were fabricated, showing the potential of this new class of quinoids as organic semiconductors.

We developed a method for the preparation of (diacetoxyiodo)-2-(N-alkylamido)benzene as an aniline-type hypervalent iodine(III). We also achieved direct cyclizations via C-H bond abstraction, such as the Hofmann-Loffler-Freytag reaction, a direct amination, and a direct lactonization, using the aniline-type hypervalent iodine(III) to obtain corresponding products in high yields.

A practical, efficient, and mild hydrogenation of levulinic acid (LA) to gamma-valerolactone (GVL) under 1 atm H-2 was realized by single-sited 3D porous self-supported N-heterocyclic carbene iridium catalysts. Quantitative yields and selectivities were achieved at 0.02 mol% catalyst loading, and the catalyst could be reused for 9 runs without obvious loss of selectivity or activity.

Controlled, photocatalytic C-H bond activations are key reactions in the toolkits of the modern synthetic chemist. While it is known that the uranyl(VI) ion, [(UO2)-O-VI](2+), the environmentally dominant form of uranium, is photoactive, most literature examines its luminescent properties, neglecting its potential synthetic utility for photocatalytic C-H bond cleavage. Here, we synthesise and fully characterise an air-stable and hydrocarbon-soluble uranyl phenanthroline complex, [(UO2)-O-VI(NO3)(2)(Ph(2)phen)], U-Ph2phen, and demonstrate that it can catalytically abstract hydrogen atoms from a variety of organic substrates under visible light irradiation. We show that the commercially available parent complex, uranyl nitrate ([(UO2)-O-VI(NO3)(2)(OH2)(2)]center dot 4H(2)O; U-NO3), is also competent, but from electronic spectroscopy we attribute the higher rates and selectivity of U-Ph2phen to ligand-mediated electronic effects. Ketones are selectively formed over other oxygenated products (alcohols, etc.), and the catalytic oxidation of substrates containing a benzylic C-H position is particularly improved for U-Ph2phen. We also show uranyl-mediated photocatalytic C-C bond cleavage in a model lignin compound for the first time.

Catalyst-free, additive-free and light-free aerobic conversion of benzylic C-H to C?O bonds is reported. A series of C-H bonds in diphenylmethanes and benzyl ethers underwent this transformation to give the targeted products in low to high yields. The reaction mechanism was also investigated using radical trapping, DFT calculations and O-18-labelled experiments, and the results suggested that the present reaction relied on an activation of oxygen by the bond of the benzene ring.

An article Synthesis of Poly(Arylene Alkenylene)s by Pd-Catalyzed Three-Component Coupling Polycondensation of Diiodoarenes, Non-Conjugated Dienes, and Nucleophiles that Involves Chain Walking Isomerization WOS:000490302000001 published article about ALLYLIC AMINES; ARYL IODIDES; POLYMERIZATION; POLYMERS; COMPLEX; ETHYLENE; CYCLOPOLYMERIZATION; COPOLYMERIZATION; POLYETHYLENES; ALKYLENE)S in [Tan, Liyi; Takeuchi, Daisuke; Osakada, Kohtaro] Tokyo Inst Technol, Lab Chem & Life Sci, R1-03,4259 Nagatsuta, Yokohama, Kanagawa 2268503, Japan; [Takeuchi, Daisuke] Hirosaki Univ, Grad Sch Sci & Technol, Dept Frontier Mat Chem, 3 Bunkyo Cho, Hirosaki, Aomori 0368561, Japan in , Cited 41.

The Pd-catalyzed three-component coupling polycondensation of diiodoarenes, nonconjugated dienes, and carbonucleophiles afforded poly(arylene alkenylene)s with moderate molecular weight in good yield. The reaction involves Mizoroki-Heck coupling, olefin migration via chain walking, and addition of the carbonucleophile to the resulting pi-allylpalladium species. The polymerization with a slight excess of nucleophile with respect to diiodoarene also proceeded to give the polymer without significant decrease in molecular weight in spite of the nonstoichiometric mixture of the monomers. The Pd-catalyzed three-component coupling polycondensation of diiodoarenes, nonconjugated dienes, and diimide also proceeded. The base used in the reaction is critical for yield and molecular weight of the product. The reaction using NaHCO3 afforded the product with low solubility, which can be explained by the high molecular weight of the polymer and/or the strong interaction of the electron donating dimethoxyphenylene groups and electron accepting diimide groups in the polymer.

Melanin is a natural pigment that is produced by filamentous fungi. In this study, the endophytic species, Spissiomyces endophytica (strain SDBR-CMU319), produced a brownblack pigment in the mycelia. Consequently, the pigment was extracted from the dried fungal biomass. This was followed by pigment purification, characterization and identification. Physical and chemical characteristics of the pigment showed acid precipitation, alkali solubilization, decolorization with oxidizing agents, and insolubility in most organic solvents and water. The pigment was confirmed as melanin based on ultraviolet-visible spectroscopy, Fourier-transform infrared, and electron paramagnetic resonance spectra analyses. The analyses of the elemental composition indicated that the pigment possessed a low percentage of nitrogen, and therefore, was not 3,4-dihydroxyphenylalanine melanin. Inhibition studies involving specific inhibitors, both tricyclazole and phthalide, and suggest that fungal melanin could be synthesized through the 1,8-dihydroxynaphthalene pathway. The optimum conditions for fungal pigment production from this species were investigated. The highest fungal pigment yield was observed in glucose yeast extract peptone medium at an initial pH value of 6.0 and at 25 degrees C over three weeks of cultivation. This is the first report on the production and characterization of melanin obtained from the genus Spissiomyces.

Phthalides and ,-butenolides are two related classes of oxygenated heterocycles with a wide range of biological activities. An innovative strategy to prepare these compounds is based on CH bond functionalization reactions, in which two simple, unfunctionalized molecules are coupled together with cleavage of a CH bond and formation of a CX bond (X=C or heteroatom). This paper reviews the methods for the synthesis of phthalides and ,-butenolides by CH bond functionalization from non-halogenated starting materials. Over 30 methods are reported, mostly developed during the past ten years.

Background: Dipeptidyl peptidase-4 (DPP-4) inhibitors have emerged as anti-hyperglycemic agents that improve glycemic control in type 2 diabetic patients, either as monotherapy or in combination with other antidiabetic drugs. Methods: A novel series of dihydropyrimidine phthalimide hybrids was synthesized and evaluated for their in vitro and in vivo DPP-4 inhibition activity and selectivity using alogliptin as reference. Oral glucose tolerance test was assessed in type 2 diabetic rats after chronic treatment with the synthesized hybrids +/- metformin. Cytotoxicity and antioxidant assays were performed. Additionally, molecular docking study with DPP-4 and structure activity relationship of the novel hybrids were also studied. Results: Among the synthesized hybrids, 10g, 10i, 10e, 10d and 10b had stronger in vitro DPP-4 inhibitory activity than alogliptin. Moreover, an in vivo DPP-4 inhibition assay revealed that 10g and 10i have the strongest and the most extended blood DPP-4 inhibitory activity compared to alogliptin. In type 2 diabetic rats, hybrids 10g, 10i and 10e exhibited better glycemic control than alogliptin, an effect that further supported by metformin combination. Finally, 10j, 10e, 10h and 10d had the highest radical scavenging activity in DPPH assay. Conclusions: Hybrids 10g, 10i and 10e are potent DPP-4 inhibitors which may be beneficial for T2DM treatment.
