Combining the encapsulating capability of cyclodextrin and instinctive features of bentonite clay, a versatile metal free catalyst has been developed that could promote various chemical reactions such as Knoevenagel condensation, synthesis of xanthan and octahydroquinazolinones in aqueous media under ultrasonic irradiation. To prepare the catalyst, bentonite was Cl-functionalized and then reacted with isatin and guanidine successively to furnish amino functionalized bentonite. The latter then reacted with tosylated cyclodextrin. The resultant catalytic composite was characterized via XRD, SEM, EDS, BET, elemental mapping analysis, TGA and FTIR. The catalytic activity tests approved excellent activity of the catalyst as well as broad substrate scope. Notably, the catalyst could be simply recovered and reused for several reaction runs. Moreover, the activity of the composite was superior to that of its components.

Predicting the acute toxicity of a large dataset of diverse chemicals against fathead minnows (Pimephales promelas) is challenging. In this paper, 963 organic compounds with acute toxicity towards fathead minnows were split into a training set (482 compounds) and a test set (481 compounds) with an approximate ratio of 1 : 1. Only six molecular descriptors were used to establish the quantitative structure-activity/toxicity relationship (QSAR/QSTR) model for 96 hourpLC(50)through a support vector machine (SVM) along with genetic algorithm. The optimal SVM model (R-2= 0.756) was verified using both internal (leave-one-out cross-validation) and external validations. The validation results (q(int)(2)= 0.699 andq(ext)(2)= 0.744) were satisfactory in predicting acute toxicity in fathead minnows compared with other models reported in the literature, although our SVM model has only six molecular descriptors and a large data set for the test set consisting of 481 compounds.

Here, we report the reaction between N-phenyl-o-phenylenediamine and pyrrole-2-carboxaldehyde to afford the N-phenyl-o-phenyl-enediiminopyrrole ligand {L-H2} in quantitative yield. A one-pot reaction between {L-H2} and diethylzinc (ZnEt2) in a 2:1 ratio afforded the homoleptic zinc metal complex [{L-H}(2)Zn] (1). The solid-state structures of ligand {L-H2} and zinc complex 1 were confirmed using X-ray crystallography. Further, complex 1 was used for chemoselective hydroboration of aldehydes and ketones in the presence of pinacolborane (HBpin) at ambient temperature to produce the corresponding boronate esters in high yield.

Aldehyde groups enable facile conjugation to proteins, enzymes, oligonucleotides or fluorescent dyes, yet there are no literature examples of water-soluble aldehyde-functional vinyl monomers. We report the synthesis of a new hydrophilic cis-diol-based methacrylic monomer (GEO5MA) by transesterification of isopropylideneglycerol penta(ethylene glycol) using methyl methacrylate followed by acetone deprotection via acid hydrolysis. The corresponding water-soluble aldehyde monomer, AGEO5MA, is prepared by aqueous periodate oxidation of GEO5MA at 22 degrees C. RAFT polymerization of GEO5MA yields the water-soluble homopolymer, PGEO5MA. Aqueous periodate oxidation of the terminal cis-diol units on PGEO5MA at 22 degrees C affords a water-soluble aldehyde-functional homopolymer (PAGEO5MA). Moreover, a library of hydrophilic statistical copolymers bearing cis-diol and aldehyde groups was prepared using sub-stoichiometric periodate/cis-diol molar ratios. The aldehyde groups on PAGEO5MA homopolymer were reacted in turn with three amino acids to demonstrate synthetic utility.

Construction and application of novel hydrogenation catalysts is important for the conversion of carbonyl or aldehyde compounds into alcohols in the field of biomass utilization. In this work, a novel, efficient, and easily prepared hafnium-graphite oxide (Hf-GO) catalyst was constructed via the coordination between Hf4+ and the carboxylic groups in GO. The catalyst was applied into the hydrogenation of biomass derived carbonyl compounds via the Meerwein-Ponndorf-Verley (MPV) reaction. The catalyst gave high efficiency under mild conditions. An interesting phenomenon was found whereby the activity of the catalyst increased gradually in the initial stage during reaction. The solvent, isopropanol, was proved to have an activation effect on the catalyst, and the activation effect varied with different alcohols and temperatures. Further characterizations showed that isopropanol played the activation effect via replacing the residual solvent (DMF) in micro- and mesopores during the preparation process, which was hard to be completely removed by common drying process.

Background: Malaria is a growing infectious disease burden due to the increasing emergence of resistant strains of Plasmodium falciparum. Because of the limited therapeutic efficacy of available antimalarial drugs, the development of potent antimalarial drug agents is therefore an urgent requirement to fight against resistant malaria. Objective: The objective of this work was to develop novel quinoline-baed antimalarial agents that would be active against resistant P. falciparum malaria. Methods: Some 7-chloro-4-(2-(substituted benzylidene)hydrazineyl)quinolines were synthesized for the evaluation of their potential as possible antimalarial agents, particularly against resistant malaria. The antimalarial activity of synthesized compounds was evaluated in vitro against bloodstage parasites of P. falciparum. Further, molecular docking and drug-likeness including ADMET (Absorption, Distribution, Metabolism, Elimination and Toxicity) studies were also carried out using in silico tools. Results: Results reveal the in vitro antimalarial activity of synthesized 7-chloro-4-(2-(substituted benzylidene)hydrazineyl)quinolines against P. falciparum. The docking study investigates the antimalarial effectiveness of synthesized quinolines as novel plasmepsin 2 inhibitors. Drug-likeness prediction exhibits acceptable drug-likeness and ADMET properties. Conclusion: Based upon our findings, it is concluded that the molecular scaffold of 7-chloro-4-(2(substituted benzylidene)hydrazineyl)quinolines may be used as a lead structure for further modifications in the search of more potent antimalarial drug molecules.

A redox-active iminoquinone motif connected with pi-delocalized pyrene core has been reported that can perform efficient two-electron oxidation of a class of substrates. The design of the molecule was inspired by the organic redox cofactor topaquinone (TPQ), which executes amine oxidation in the enzyme, copper amine oxidase. Easy oxidation of both primary and secondary alcohols happened in the presence of catalytic KOtBu, which could reduce the ligand backbone to its iminosemiquinonate form under photoinduced conditions. Moreover, this easy oxidation of alcohols under aerobic condition could be elegantly extended to multi-component, one-pot coupling for the synthesis of quinoline and pyrimidine. This organocatalytic approach is very mild (70 degrees C, 8 h) compared to a multitude of transition-metal catalysts that have been used to prepare these heterocycles. A detailed mechanistic study proves the intermediacy of the iminosemiquinonate-type radical and a critical hydrogen atom transfer step to be involved in the dehydrogenation reaction.

Chiral ionic liquids (CILs) have shown a wide range of applications in variety of domains in chemistry. Because of this, synthesis and applications of CILs have always been areas of interest for research in the last 20 years. Present work describes, the synthesis of six carbohydrate based chiral ionic liquids (CCILs) by following simple procedures and their applications. Structures of the cats were confirmed through various analytical techniques like NMR spectroscopy (H-1, C-13, B-11, P-31,F-19), El-MS, and polarimetry. Designed CCILs were tested as chiral recognising agents using sodium salt of Mosher’s acid as model substrate through (FNMR)-F-19-N- spectroscopy. Further, Cats were used as organocatalyst in the enantioselective reduction of aromatic prochiral ketones to achieve corresponding chiral secondary alcohols. (C) 2019 Elsevier B.V.
