The development of an efficient system for selective oxidation of organic compounds to generate more valuable compounds with molecular oxygen is a significant challenge in industrial chemistry. Bioinspired by the ability of naturally occurring perylenequinonoid pigments (PQPs) to generate reactive oxygen species (ROS) upon photoirradiation, here we report that cercosporin, one of the perylenequinonoid pigments, can function as a cost-effective and environmentally friendly photocatalyst for a wide range of selective oxidations, including benzylic C-H bonds to carbonyls, amines to aldehydes, and sulfides to sulfoxides. All of the representative reactions proceeded smoothly with high efficiency under mild conditions. Owing to the use of inexpensive metal-free visible light-driven photocatalyst produced from microbial fermentation with cheap glucose as the starting material and the ease of handling, we expect that this developed method will be particularly attractive for many more applications in synthetic transformation.

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.

Phthalides as the crucial core skeletons are found extensively in natural products and biological active molecules. Herein we disclose an asymmetric allylation of 3-hydroxyisoben-zofuran-1(3H)-ones with boron allylation reagents to construct chiral phthalide derivatives. The simple Bi(OAc)(3)/chiral phosphoric acid catalytic system proves to be efficient in this method, delivering the desired chiral 3-allylisobenzofuran-1(3H)-ones in good yields (up to 99%) and high enantioselectivities (up to 99.5:0.5 e.r.) under mild conditions. The large-scale reaction and diverse transformations of products to various scaffolds with potential biological activities render it more attractive. Moreover, the mechanism was preliminarily explored by control reactions, mass spectrometry, deuterium experiment, and DFT calculations.

Air-stable iron carbonyl compounds bearing cyclo-pentadienone ligands with varying substitution were explored ,as catalysts in dehydrogenative diol lactonization reactions using acetone as both the solvent and hydrogen acceptor. Two catalysts with trimethylsilyl groups in the 2- and 5-positions, [2,S-(SiMe3)(2)-3,4-(CH2)(4)(eta(4)-C4C=O))Fe(CO)(3) (1) and [2,5-(SiMe3)(2)-3,4(CH2)(3)(eta(4)-C4C=O)]Fe(CO)(3) (2), were found to be the most active, with 2 being the most selective in the lactonization of diols containing both primary and secondary alcohols. Lactones containing five-, six-, and seven-membered rings .were successfully synthesized, and no over-oxidations to carboxylic acids were detected. The lactonization of unsymmetrical diols containing two primary alcohols occurred with catalyst 1, but selectivity was low based on alcohol electronics and modest based on alcohol sterics. Evidence for a transfer dehydrogenation mechanism was found, and insight into the origin of selectivity in the lactonization of 1 degrees/2 degrees diols was obtained. Additionally, spectroscopic evidence for a trimethylamine-ligated iron species formed in solution during the reaction was discovered.

We report the conversion of a series of CNN-pincer-ruthenium complexes Ru(CNN)HCl(CO) to a CC-chelated form Ru(CC)(PR3)(2)H(CO) on reaction with sodium tert-butoxide and monodentate phosphines. When the phosphine is triphenylphosphine, cis-phosphine complexes form at room temperature, which convert to the trans isomer at elevated temperatures. When the phosphine is tricyclohexylphosphine, only the trans-phosphine isomer is observed. The CC-chelated complexes are active catalysts for the hydrogenation of esters, without the need for added base. The ligand structure-activity relationship in the series of CC-chelated complexes mirrors that in the precursor CNN-Ru complexes, potentially indicating a common catalytic mechanism. Density functional theory calculations establish a plausible mechanism for the CNN-to-CC rearrangement and demonstrate that this rearrangement is potentially reversible under the conditions of ester hydrogenation catalysis.

Atherosclerosis is initiated by the local inflammation response to lipid deposition, and the most commonly administered antiatherogenic drugs are statins. Based on traditional Chinese medicine (TCM) evidence, we aimed to find effective therapeutic agents other than statins. A TCM, Suxiao Jiuxin Pill (SX), has been widely used in curing cardiovascular diseases for thirty years. In this paper, a combination of pharmacologic studies and RNA-Seq transcriptomics were employed to explore the pharmacodynamic advantages of SX over atorvastatin in the ApoE(-/-) mouse. 113 differentially expressed genes that were modulated by SX to a greater degree than atorvastatin were primarily involved in immunomodulation. The expression of BTK, AKT1, c-jun and CD137 was effectively regulated by SX with better effect than atorvastatin. Then a dual-luciferase reporter assay for NF-kappa B inhibition was applied to identify active components in SX. As a result, Senkyunolide A (Sen A) and Ligustilide (Lig), the key immunomodulatory ingredients in SX, were found to inhibit the expression of CD137 which is a diagnostic biomarker in atherosclerosis. It was further confirmed that Lig effectively suppressed the expression of AP-1 and NF-kappa B and the phosphorylation of AKT. Therefore, Lig achieved its CD137 inhibition through suppressing the expression of AP-1 and AKT/NF-kappa B signaling pathway, which partly explains the immunomodulation of SX in atherosclerosis. Above all, phthalides may be the primary components of SX improving immune and inflammation response in atherosclerosis.

Considering the anti-infective potential of compounds containing the dibenzothiepine scaffold, we set out to obtain new compounds bearing this structure. The synthesized compounds were characterized by spectral studies and elemental analysis and screened for their microbiostatic/microbicidal and antibiofilm properties against reference and clinical microbial strains. The new compounds exhibited a broad spectrum of antimicrobial activity, which was more intensive for the S-oxidized compounds. Some of the compounds also inhibited the ability of the investigated strains to form biofilms on the inert substratum.
