The direct esterification of alcohols with non-noble metal-based catalytic systems faces great challenges. Here, we report a new chrome-based catalyst stabilized by a single pentaerythritol decorated Anderson-type polyoxometalate, [N(C4H9)(4)](3)[CrMo6O18(OH)(3)C{(OCH2)(3)CH2OH}], which can realize the efficient transformation from alcohols to esters by H2O2 oxidation in good yields and high selectivity without extra organic ligands. A variety of alcohols with different functionalities including some natural products and pharmaceutical intermediates are tolerated in this system. The chrome-based catalyst can be recycled several times and still keep the original configuration and catalytic activity. We also propose a reasonable catalytic mechanism and prove the potential for industrial applications.

Effective Protein A column regeneration is important in therapeutic monoclonal antibody (mAb) production for product quality and process economics. To design a robust and effective regeneration strategy, resin compatibility, microbial inactivation efficiency and cleaning effectiveness are three major considerations. Regenerating Protein A column using acidic (e.g. acetic acid) and/or caustic (e.g. NaOH) solutions is a common approach. However, it is challenging to balance between resin performance decline and adequate microbial control in choosing the right caustic solution concentration, even for resin with enhanced caustic tolerance such as MabSelect SuRe. This report introduces an enhanced regeneration strategy for MabSelect SuRe resin. The approach applies benzyl alcohol in low concentration acetic acid and NaOH (100 mM) solutions in sequential steps to regenerate MabSelect SuRe resin for reuse. Such solutions demonstrated good resin compatibility in resin functional test after extended solution incubation time, and demonstrated superior microbial control using eight test microorganisms. The cleaning effectiveness of the proposed strategy is demonstrated by carryover study, where product and impurity carryover was below detection limit. Finally, during a resin lifetime study, consistent step yields and product quality attributes were demonstrated, and no carryover was observed, up to 150 purification cycles. A viral clearance study further demonstrated that aged resin at the end of the resin lifetime had comparable viral clearance performance compared to new resin. No active virus was detected in the elution pool of the subsequent blank runs. These studies further verified the robustness of the proposed regeneration strategy for MabSelect SuRe resin.

A series of Ephedra based oxadiazinones have been prepared, acylated, and examined in the asymmetric conjugate addition reaction with Grignard reagents in the presence of copper(I) bromide-dimethyl sulfide complex. The highest diastereoselectivity that was obtained in the conjugate addition reaction was observed with the (1R,2S)-ephedrine based N-4-methyloxadiazinone (5:1 d.r.) favoring the formation of the (S)-configuration of the conjugate addition product. Efforts to enhance the level of diaster-eoselection via increasing the steric volume of the stereo-directing N-4-substituent of the oxadiazinone (N-4- = p-methoxyphenyl or -isopropyl) led to an observed decrease in the level of diastereoselection. A computational study was conducted to examine the conformations adopted by the N-4-methyloxadiazinone vs. the N-4-isopropyl-oxadiazinone that yielded the lower diastereoselectivity. An argument is made for the stereoelectronic properties of the N-4-substituent being the cause of both the moderate diastereoselectivity and the unexpected facial preference for the conjugate addition.

The present study describes the synthesis of the first phenoxycalix[4]pyrrole-epichlorohydrin based polymer. The advantage of the latter resides in its fast-single step synthesis protocol, low cost, water insolubility and its unexpected anion extraction capacity. The study of this polymer by various solid/liquid extractions with halides in aqueous solutions and quantitative ion chromatography analysis showed that unlike other calix[4]pyrrole-based entities, this polymer extracts iodide rather than bromide and fluoride owing to the presence of large extraction pockets. Evidence of an anion exchange process involving preferably chloride and bromide was also highlighted.

The preparation of homoallylic alcohols by addition of organometallic allyl compounds to carbonyls is an important strategy in organic chemistry. Allylating organometallic cobalt species can be generated employing stoichiometric quantities of Zn acting as reductant. To avoid the employment of stoichiometric amount of Zn, we have developed an allylation reaction of aromatic and aliphatic aldehydes promoted by photoredox catalysis in the presence of a cobalt complex, and we present herein a full account of our research. In the presence of the abundant CoBr2 (10 mol %), 4,4 ‘-di-tert-butyl-2,2 ‘-dipyridyl (dtbbpy, 10 mol %), allyl acetate (3 equiv.), [Ir(dtbbpy)(ppy)(2)]PF6 (ppy=2-phenylpyridine, 2 mol %), and N,N-diisopropylethylamine (4 equiv.), an allylation of aldehydes is taking place, in moderate to good yields. Substrates scope, limitations, and photophysical investigations of this new process are reported.

In this study, we present a versatile and easy procedure for modifying a cobalt ferrite nanoparticle step by step. A new nanocatalyst was prepared via Cu(II)immobilized onto CoFe2O4@HT@Imine. The catalyst was fully characterized by Fourier-transform infrared (FT-IR), energy-dispersive X-ray spectroscopy (EDX), field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and vibrating sample magnetometer (VSM) analyses. The current procedure as a green protocol offers benefits including a simple operational method, an excellent yield of products, mild reaction conditions, minimum chemical wastes, and short reaction times. Without any significant reduction in the catalytic performance, up to five recyclability cycles of the catalyst were obtained. The optimization results suggest that the best condition in the oxidation of benzyl alcohol derivatives is 0.003 g of the CoFe2O4@HT@Imine-Cu(II)catalyst, TEMPO, at 70 degrees C under solvent-free condition and air.

Converting lignite into soluble organic compounds (SOCs) under mild conditions is significant for both evaluating molecular structure and producing clean fuels/chemicals. A three-step dissociation, i.e., sequential extraction, sequential thermal dissolution (TD), and ruthenium-ion-catalyzed oxidation (RICO), was adopted to convert the organic matter (OM) in Xiaolongtan lignite (XL) into SOCs. The perspectives on chemicals, geo-chemical information, and structural characteristics of XL were evaluated based on the molecular compositions of SOCs. Much higher yields of SOCs were obtained from TD than from extraction, which could be attributed to the thermal dissociation of non-covalent interactions in XL. Normal alkanes, alkyl-substituted benzenes, alkyl substituted phenols, ketones, and aliphatic esters are the main group components released from TD. A series of important biomarkers were released and their distributions and evolution pathways during XL-forming process imply that higher terrestrial plants could be the main input of the OM in XL. Benzenecarboxylic acids were produced from TD residue in high selectivity via the RICO. According to the results from the RICO, the insoluble macromolecular structures in XL are rich in peri-condensed aromatics along with some cata-condensed aromatics and polyaryls, and -CH3 is the major alkyl side chain on the aromatic rings. Adjacent aromatic moieties are mainly connected each other directly by C-ar-C-ar bridged bonds.

Two different sustainable and efficient synthetic methods have been developed for the synthesis of a variety of 3-aminoimidazo fused heterocycles by one-pot three component reaction of 2-aminoazines, aldehydes and isocyanides. The methods adopted were (a) aqueous micellar mediated condition (method A) (b) VB(1)catalyzed reaction under solvent-free condition (method B). Excellent yields were obtained for a broad range of biologically significant imidazopyridine core molecules under green conditions at room temperature. Synthesis in aqueous micellar medium, mild reaction conditions, organocatalyst, easy work-up and isolation, and gram scale synthesis, are some of the advantages of these protocols.

Lantana camara (L.) is employed by several ethnical groups to treat numerous diseases. Although there are no ethnomedical reports on its use against leishmaniasis, organic extracts prepared from L. camara were shown to display leishmanicidal activity. In the present study, we carried out a bioassay-guided fractionation of the dichloromethane extract from Mexican L. camara in order to identify the compounds responsible for the leishmanicidal activity. Eighteen chromatographic fractions (FI-FXVIII) were evaluated in vitro against Leishmania mexicana and L. amazonensis. FII, FX, FXI, FXV, and FXVI showed significant activity against both Leishmania strains, the most potent of which was FXV. Eicosane (1), squalene (2), -ionone (3), caryophyllene oxide (4), -caryophyllene (5), hexanoic acid (6), tiglic acid (7), a mixture of lantanilic (8) and camaric (9) acids, and lantadene B (10) were identified and obtained from the active fractions and evaluated for their leishmanicidal activity. The mixture of lantanilic (8) and camaric (9) acids (79%/21%) was the most potent one (half maximal inhibitory concentration (IC50) = 12.02 +/- 0.36 M). This study indicates that this cultivar of L. camara has high potential for the development of phytomedicines or as a source of natural products, which might represent lead compounds for the design of new drugs against leishmaniasis.
