Co/Al2O3-EPM (i.e., prepared by electroless plating method) is a new potential catalyst with high catalytic capacity and stability, which has not been used for peroxymonosulfate (PMS) activation. In this study, the sulfamethoxazole (SMX) in aqueous solution was degraded by the Co/Al2O3-EPM/PMS system. First, characteristics of Co/Al2O3-EPM were analyzed by using X-ray powder diffraction (XRD), Fourier transform infrared (FTIR) and X-ray photoelectron spectroscopy (XPS). Then, the key parameters of Co/Al2O3-EPM dosage, PMS dosage and initial pH were optimized, respectively. The maximum SMX removal (98.5%) and total organic carbon (TOC) removal (25.6%) were obtained under the optimal conditions of Co/Al2O3-EPM = 0.8 g/L, PMS = 0.2 mM, initial pH = 6.3 and treatment time = 10 min. Also, the ions effects in Co/Al2O3-EPM/PMS system for SMX removal were investigated integrally. Besides, three control experiments (i.e., Co/Al2O3-EPM alone, PMS alone and homogeneous Co(II)/PMS systems) were conducted under the optimal conditions to verify the superiority of Co/Al2O3-EPM/PMS system. Furthermore, the degradation pathways of SMX were proposed according its intermediates detected by high performance liquid chromatography-mass spectrometry (HPLC-MS), and their biological toxicity were evaluated by activated sludge. In addition, the free radical identification experiment confirms that sulfate radical (SO4[rad]?) was the dominant active matter for SMX removal. The generation of SO4[rad]? during the reaction process in Co/Al2O3-EPM/PMS system was quantified indirectly via high performance liquid chromatography (HPLC). Finally, the possible reaction mechanism of Co/Al2O3-EPM/PMS system for SMX removal was proposed thoroughly. In brief, this study provided a new catalyst for PMS activation and all the results confirm that Co/Al2O3-EPM is a robust and high efficient catalyst for PMS activation.

A concise, regiocontrolled route to isoxazoles, based on the condensation of an ester with a metallated imine, has been developed. The intermediate vinylogous amides react smoothly with hydroxylamine to provide, after dehydration, substituted isoxazoles. The method has been used for the multi-kilo scale preparation of ABT-418, a novel cholinergic channel activator.

Protoporphyrinogen oxidase (PPO) has been identified as one of the most promising targets for herbicide discovery. A series of novel phthalimide derivatives were designed by molecular docking studies targeting the crystal structure of mitochondrial PPO from tobacco (mtPPO, PDB: 1SEZ) by using Flumioxazin as a lead, after which the derivatives were synthesized and characterized, and their herbicidal activities were subsequently evaluated. The herbicidal bioassay results showed that compounds such as 3a (2-(4-bromo-2,6-difluorophenyl)isoindoline-1,3-dione), 3d (methyl 2-(4-chloro-1,3-dioxoisoindolin-2-yl)-5-fluorobenzoate), 3g (4-chloro-2-(5-methylisoxazol-3-yl) isoindoline-1,3-dione), 3j (4-chloro-2-(thiophen-2-ylmethyl)isoindoline-1,3-dione) and 3r (2-(4-bromo-2,6-difluorophenyl)-4-fluoroisoindoline-1,3-dione) had good herbicidal activities; among them, 3a showed excellent herbicidal efficacy against A. retroflexus and B. campestris via the small cup method and via pre-emergence and post-emergence spray treatments. The efficacy was comparable to that of the commercial herbicides Flumioxazin, Atrazine, and Chlortoluron. Further, the enzyme activity assay results suggest that the mode of action of compound 3a involves the inhibition of the PPO enzyme, and 3a showed better inhibitory activity against PPO than did Flumioxazin. These results indicate that our molecular design strategy contributes to the development of novel promising PPO inhibitors.

A transition-metal-free intramolecular dehydrohalide coupling via intramolecular homolytic aromatic substitution (HAS) with aryl radicals has been developed in the presence of potassium tert-butoxide and an organic molecule as the catalyst. The methodology has been applied to a concise synthesis of Amaryllidaceae alkaloids viz. oxoassoanine (1b), anhydrolycorinone (1d), and other related structures. Interestingly, the method also works only in the presence of potassium tert-butoxide.

(Chemical Equation Presented) A short stereoselective total synthesis of the polyketide natural product, tarchonanthuslactone, has been achieved. The key sequence involves the first reported catalytic enantioselective reduction of an N-acyl pyrrole and subsequent use of this stereocenter in a diastereoselective reductive cascade.

Sphingosine 1-phosphate (S1P) is the endogenous ligand for the sphingosine 1-phosphate receptors (S1P1-5) and evokes a variety of cellular responses through their stimulation. The interaction of S1P with the S1P receptors plays a fundamental physiological role in a number of processes including vascular development and stabilization, lymphocyte migration, and proliferation. Agonism of S1P1, in particular, has been shown to play a significant role in lymphocyte trafficking from the thymus and secondary lymphoid organs, resulting in immunosuppression. This article will detail the discovery and SAR of a potent and selective series of isoxazole based full agonists of S1P1. Isoxazole 6d demonstrated impressive efficacy when administered orally in a rat model of arthritis and in a mouse experimental autoimmune encephalomyelitis (EAE) model of multiple sclerosis.
