Methods for selective C-H bond functionalization have provided chemists with versatile and powerful toolboxes for synthesis, such as the late-stage modification of a lead compound without the need for lengthy de novo synthesis(1-5). Cleavage of an sp(3) C-H bond via hydrogen atom transfer (HAT) is particularly useful, given the large number of available HAT acceptors and the diversity of reaction pathways available to the resulting radical intermediate(6-17). Site-selectivity, however, remains a formidable challenge, especially among sp(3) C-H bonds with comparable properties. If the intermediate radical could be further trapped enantioselectively, this should enable highly site- and enantioselective functionalization of C-H bonds. Here we report a copper (Cu)-catalysed site- and enantioselective allylic C-H cyanation of complex alkenes, in which a Cu(ii)-bound nitrogen (N)-centred radical plays the key role in achieving precise site-specific HAT. This method is shown to be effective for a diverse collection of alkene-containing molecules, including sterically demanding structures and complex natural products and pharmaceuticals.

Azetidines are valuable motifs that readily access under explored chemical space for drug discovery. 3,3-Diarylazetidines are prepared in high yield from N-Cbz azetidinols in a calcium(II)-catalyzed Friedel-Crafts alkylation of (hetero)aromatics and phenols, including complex phenols such as beta-estradiol. Electron poor phenols undergo O-alkylation. The product azetidines can be derivatized to drug-like compounds through the azetidine nitrogen and the aromatic groups. The N-Cbz group is crucial to reactivity by providing stabilization of an intermediate carbocation on the four-membered ring.

Etoxazole is a newly registered and widely used acaricide. However, its metabolites were not fully understood and might exhibit similar or even higher toxicity than parent compound. Therefore, in this study, the metabolites of etoxazole in citrus, soil and earthworms were firstly identified by an ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS). Four potential metabolites in citrus, 11 in soil, and 8 in earthworms were determined. These metabolites were then further structural elucidated based on the fragment pathways, and accurate mass measurement. The distributions of etoxazole and its main metabolites (M1, M2, M3, M4 and M5) which were identified as the dehydrogenation, hydrolysis, oxidation products of etoxazole (M0) were also monitored in citrus, soil and earthworms at different exposure periods. The 45 days exposure experiment showed that M0 gradually decreased in citrus and soil samples by 80% and 28% of the initial amounts, respectively. In earthworm samples, M0 accumulated in the bodies of the worms during 24 days exposure and then decreased with time. The dissipation rate of etoxazole were citrus > earthworms > soil. Concentrations of M1 and M3 in soil were found continuously increased with time during the experimental period. Moreover, the persistence of M1 in earthworm samples was also observed. Great attention should be paid to these two compounds due to their potential risks to both environmental and human health. (C) 2019 Published by Elsevier Ltd.

Photocatalytic reduction of molecular oxygen is a promising route toward sustainable production of hydrogen peroxide (H2O2). This challenging process requires photoactive semiconductors enabling solar energy driven generation and separation of electrons and holes with high charge transfer kinetics. Covalent organic frameworks (COFs) are an emerging class of photoactive semiconductors, tunable at a molecular level for high charge carrier generation and transfer. Herein, we report two newly designed two-dimensional COFs based on a (diarylamino)benzene linker that form a Kagome (kgm) lattice and show strong visible light absorption. Their high crystallinity and large surface areas (up to 1165 m(2)center dot g(-1)) allow efficient charge transfer and diffusion. The diarylamine (donor) unit promotes strong reduction properties, enabling these COFs to efficiently reduce oxygen to form H2O2. Overall, the use of a metal-free, recyclable photocatalytic system allows efficient photocatalytic solar transformations.

A collection of N-substituted quinolin-2(1H)-ones were screened against a panel of clinically relevant protozoa (Leishmania, Trypanosoma and Acanthamoeba). Three quinolin-2(1H)-one compounds were identified as selective anti-Acanthamoeba agents. Further assessment revealed that these compounds were active against both trophozoite and cyst forms of A. castellanii Neff, and caused protozoa death via apoptosis. The data presented herein identify N-acyl quinolin-2(1H)-ones as a promising new class of selective anti-Acanthamoeba agents.

Activation of carbonyl moiety is one of the most rudimentary approaches in organic synthesis and is crucial for a plethora of industrial-scale condensation reactions. In esterification and aldol condensation, which represent two of the most important reactions, the susceptibility of the carbonyl group to nucleophile attack allows the construction of a variety of useful organic compounds. In this context, there is a constant need for development of and improvement in the methods for addition-elimination reactions via activation of carbonyl functionality. In this paper, an advanced methodology for the direct esterification of carboxylic acids and alcohols, and for aldol condensation of aldehydes using widely available, inexpensive, and metal-free 1,3-dibromo-5,5-dimethylhydantoin under neat reaction conditions is reported. The method is air- and moisture-tolerant, allowing simple synthetic and isolation procedures for both reactions presented in this paper. The reaction pathway for esterification is proposed and a scale-up of certain industrially important derivatives is performed.

A site-selective supported palladium nanoparticle catalyzed Suzuki-Miyaura cross-coupling reaction with heteroaryl esters and arylboronic acids as coupling partners was developed. This methodology provides a heterogeneous catalytic route for aryl ketone formation via C(acyl)-O bond activation of esters by successful suppression of the undesired decarbonylation phenomenon. The catalyst can be reused and shows high activity after eight cycles. The XPS analysis of the catalyst before and after the reaction suggested that the reaction might be performed via a Pd-0/Pd-II catalytic cycle that began with Pd-0.

Aim: To design, synthesis and in vitro evaluation of 4-oxo-6-substituted phenyl-2-thioxo 1,2,3,4-tetrahydropyrimidine-5-carbonitrile derivatives as HIV integrase strand transfer inhibitors. Background: Human immunodeficiency virus-1 (HIV-1), a member of retroviridae family, is the primary causative agent of acquired immunodeficiency syndrome (AIDS). Three enzymes viz: integrase (IN), reverse transcriptase (RT) and protease play important role in its replication cycle. HIV-1 integrase is responsible for the incorporation of viral DNA into human chromosomal DNA by catalyzing two independent reactions, 3′-processing (3′-P) and strand transfer (ST), which are observed as the point of no-return in HIV infection. Objective: To develop inhibitors against HIV integrase strand transfer step. Methods: Our previous results indicated that tetrahydro pyrimidine-5-carboxamide derivatives are potent HIV-1 IN inhibitors (unpublished results from our laboratory). Taking clue from above studies and our own experience, we hypothesized 4-oxo-6-substituted phenyl-2-thioxo 1,2,3,4-tetrahydropyrimidine-5-carbonitrile analogues (14a to 14n) as inhibitors of HIV-1 Integrase strand transfer. Prototype compound 14 can be viewed as hybrid structure having characteristics of dihydropyrimidine derivatives 10-12 and tyrphostin 13. Results: A total of fourteen derivatives of 4-oxo-6-substituted phenyl-2-thioxo-1,2,3,4-tetrahydro-pyrimidine-5-carbonitrile (14a-14n) were synthesized and evaluated using HIV-1 Integrase Assay Kit (Xpressbio Life Science Products, USA). The percentage inhibition of all compounds was investigated at 10 mu M concentration and IC50 value of few highly active compounds was studied. The obtained results were validated by in silico molecular docking study using Glide (maestro version 9.3, Schrodinger suite) in extra precision (XP) mode. Conclusion: Fourteen 4-oxo-6-substituted phenyl-2-thioxo 1,2,3,4-tetrahydropyrimidine-5-carbonitrile analogues were synthesized and evaluated for HIV-1 IN inhibitory activity. Three compounds 14a, 14e, and 14h exhibited significant percentage inhibition of HIV-1 IN. There was good in vitro – in silico correlation. However, none of the derivative was active against HIV-1 and HIV-2 below their cytotoxic concentration. It needs to be seen whether these compounds can be explored further for their anti-HIV or cytotoxic potential.

A novel path has been developed for the conversion of carboxylic acids into the corresponding N -acylbenzotriazoles by using 2,2-dipyridyl disulfide/PPh (3) in anhydrous dichloromethane in the presence of 1 H -benzotriazole. Mild reaction conditions, short reaction time, easy in handling, wide substrate scope, availability of reagents involved, and moreover avoiding the use of base makes this protocol quite useful for the laboratory practices for N -acylbenzotriazole synthesis.
