This work examines howN-donor bridged spacer ligands affectN-heterocyclic carbene (NHC) palladium complexes catalytic activities for Suzuki coupling reaction. Different degrees of structural flexibility binuclear NHC palladium complexes were synthesized. The more flexible nitrogen-based alkyl chain ligand shows similar performance with cycloamine counterparts in the Suzuki coupling reaction. Suzuki coupling examples were used in air and ambient temperature to reach moderate to completion yields in short time. Density functional theory calculations showed that the chelate effect, associated with a single Pd complex mechanism, plays a fundamental role in the pre-catalysis stage, supporting a reasonable of the kinetic activity observed experimentally.

To obtain a pure product without the isomer byproducts is a goal that many chemists are pursuing. As one kind of very important synthesis method, the photochemical reaction is simple and straightforward yet low-selective. In this work, a coordination interaction based oriented synthesis strategy has been proposed to realize the precise stereochemical control of the isomeric cyclic compounds in the photocycloaddition reaction. Through fixing the reactants via coordination interactions, the arrangements and configurations of the reactants can be adjusted, thereby successfully producing all of the related photocycloaddition products without isomer byproducts for the first time. This work not only provides a new route to synthesize the pure cyclic compounds but also expands the application of the photocycloaddition reaction.

Synthesis of 50 analogues of the natural insecticide synergists, dillapiol and sesamol, is reported. These were evaluated as potential insecticide synergists based on their inhibition of human CYP3A4. The most potent inhibitors have a relatively large hydrophobic substituent at either position 5 or 6 of these molecules. For example, 5-(benzyloxy)-6-(3-phenylsulfonyl)propyl)benzo[d] [1,3]dioxole (18) and the diphenyl acetate of (6,7-dimethoxybenzo[d] [1,3]dioxol-5-yl)propan-1-ol (5n) show inhibitory concentrations for 50% activity IC50 values of 0.086 and 0.2 mu M, respectively. These compounds are 106 and 46 times more potent than dillapiol whose IC50 for the inhibition of CYP3A4 is 9.2 mu M. The ortho-chloro analogue (8f), whose activity is 86 times the activity of dillapiol, is the most potent of the fourteen 5-(benzyloxy-6-(2-propenyl)benzo[d][1,3]dioxoles prepared for this study.

Cocrystallization of the widely available 4-dimethylaminopyridine, with a series of carboxylic acids gave nine molecular adducts 4-dimethylaminopyridinium trifluoroacetate (1) , 4-dimethylaminopyridinium glycolate glycolic acid (2) , 4-dimethylaminopyridinium 2-furoate dihydrate (3) , tri(4-dimethylaminopyridinium) tri(o-chlorobenzoate) tetrahydrate (4) , 4-dimethylaminopyridinium 4-bromobenzoate 4-bromobenzoic acid (5) , 4-dimethylaminopyridinium 4-formylbenzoate 4-formylbenzoic acid (6) , 4-dimethylaminopyridinium 2,4-dichlorobenzoate (7) , 4-dimethylaminopyridinium 2-aminobenzoate 2-aminobenzoic acid (8) and bis(4-dimethylaminopyridinium) 5-nitroisophthalate 5-nitroisophthalic acid methanol solvate (9) . The nine adducts have been characterised by X-ray diffraction, IR and elemental analysis, the melting points were also reported. Their structural and supramolecular aspects are fully analyzed. The result reveals that among the nine investigated crystals only the ring Ns in the 4-dimethylaminopyridine moieties are protonated when the carboxylic acids are deprotonated. The crystal packing is interpreted by the strong charge-assisted N-H center dot center dot center dot O hydrogen bond between the NH+ and the deprotonated acidic groups. Except the N-H center dot center dot center dot O hydrogen bonds, the charge assisted or neutral O-H center dot center dot center dot O hydrogen bonds were also found at 2-6, 8 and 9 . The COOH center dot center dot center dot COO- synthon has been at 2, 5-6 and 8-9. Further analysis of the crystal packing indicated that a different family of additional CH-O/CH2-O/CH3-O, F-F, Br-Br, CH-Cl, CH3-Cl, CH-pi/CH3-pi, C-H center dot center dot center dot C-pi, C-pi, Cl-O, O-C, O-pi and pi-pi contacts contribute to the stabilization and expansion of the total high-dimensional (2D-3D) framework structures. For the synergism of the various nonbonding contacts there created homo/hetero supramolecular synthons or both. (C) 2021 Elsevier B.V. All rights reserved.

Novel heteroleptic Ni (II) complexes bearing a highly hindered yet flexible IPr* ligand, Ni (IPr*)(PPh3)Br-2 (1) and Ni (IPr*)(PCy3)Br-2 (2) (IPr* = 1,3-bis(2,6-bis (diphenylmethyl)-4-methylphenyl)imidazol-2-ylidene), were easily prepared in 78% and 89% yield, respectively. Both were characterized by elemental analysis and NMR spectroscopy, and 1 was subjected to X-ray crystallography. Compared with 2 and its analogue bearing a less sterically demanding IPr ligand (IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene), complex 1 exhibited superior catalytic activity in the magnesium-mediated reductive coupling of benzyl chlorides with aryl chlorides, featuring outstanding tolerance of both coupling partners with steric demand. This study discloses a ligand-facilitated reductive coupling of benzyl chlorides with aryl chlorides, which provides a new and practical synthetic tool for the synthesis of diarylmethanes.

Disposable sanitary pads are a necessity for women’s health, but safety concerns regarding the use of these products have created anxiety. The aim of this study was to conduct a risk assessment of 74 volatile organic compounds (VOCs), which were expected to be contained within sanitary pads. Of the 74 VOCs, 50 were found in sanitary pads retailed in Korea at concentrations ranging from 0.025 to 3548.09 mu g/pad. In order to undertake a risk assessment of the VOCs, the toxicological database of these compounds in the United States Environmental Protection Agency (USEPA), Agency for Toxic Substances and Disease Registry (ATSDR), National Toxicology Program (NTP) and World Health Organization (WHO) was searched. Ethanol was found to exhibit the highest reference dose (RfD) while 1,2-dibromo-3-chloro-propane displayed the lowest RfD. Consequently, a worst-case exposure scenario was applied in this study. It was assumed that there was the use of 7.5 sanitary napkins/day for 7 days/month. In the case of panty liners or overnight sanitary napkins, the utilization of 90 panty liners/month or 21 overnight sanitary napkins/month was assumed, respectively. In addition, 43 kg, the body weight of 12 to 13-year-old young women, and 100% VOCs skin absorption were employed for risk assessment. The systemic exposure dose (SED) values were calculated ranging from 1.74 (1,1,2-trichloroethane) ng/kg/day to 144.4 (ethanol, absolute) mu g/kg/day. Uncertainty factors (UFs) were applied ranging from 10 to 100,000 in accordance with the robustness of animal or human experiments. The margin of exposure (MOE) of 34 VOCs was more than 1 (acceptable MOE > 1). Applicable carcinogenic references reported that the cancer risk of five VOCs was below 10(-6). Based on our findings, evidence indicates that the non-cancer and cancer risks associated with VOCs detected in sanitary pads currently used in South Korea do not pose an adverse health risk in women.

Paeonol has been proved to have potential anti-inflammatory activity, but its clinical application is not extensive due to the poor anti-inflammatory activity (14.74% inhibitory activity at 20 mu M). In order to discover novel lead compound with high anti-inflammatory activity, series of paeonol derivatives were designed and synthesized, their anti-inflammatory activities were screened in vitro and in vivo. Structure-activity relationships (SARs) have been fully concluded, and finally (E)-N-(4-(2-acetyl-5-methoxyphenoxy)phenyl)-3-(3,4,5-trimet-hoxyphenyl) acrylamide (compound 1 la) was found to be the best active compound with low toxicity, which showed 96.32% inhibitory activity at 20 mu M and IC50 value of 6.96 mu M against LPS-induced over expression of nitric oxide (NO) in RAW 264.7 macrophages. Preliminary mechanism studies indicated that it could inhibit the expression of TLR4, resulting in inhibiting of NF-kappa B and MAPK pathways. Further studies have shown that compound 11a has obvious therapeutic effect against the adjuvant-induced rat arthritis model.

Disclosed herein is a photochemical Heck-type arylation of vinylphenols with non-activated aryl and heteroaryl halides under visible light irradiation. Preliminary mechanistic studies suggested that the colored vinylphenolate anions acted as a strong reducing photoactivator to directly activate (hetero)aryl halides without the need for any sacrificial reductants. The photochemically generated aryl radicals coupled with another molecule of vinylphenol to afford the Heck-type arylation product in a regiospecific and stereoselective manner. The developed photochemical arylation protocol showed exceptional functional group tolerance and was successfully applied in the challenging late-stage modification of natural products without any protection-deprotection procedures.
