Here we report a protocol to synthesize diversiform fluorinated isocryptolepine analogues with potential biological activities in one step via directed C-2 and C-3 dual C-H functionalization of indoles. We also attempted to take into account fluorinated imidoyl chlorides as a novel kind of synthons in the directed C-H functionalization reactions. As a result, a variety of fluorinated isocryptolepine analogues were obtained in up to 96% yield. Moreover, we conducted control experiments to disclose the reaction mechanism.

Octahedral CdS-ZnS composites were synthesized using a simple method of cation exchange and hydrothermal treatment, using Cd-3(C3N3S3)(2) (denoted as Cd-3(TMT)(2)) as a precursor and Zn2+ for ion exchange. In the spontaneous ion exchange process, there is the formation of compact heterojunctions and three-dimensional octahedral structures. By controlling the ion exchange level, the composition of (CdxZn1-x)(3) (TMT)(2) hybrid nanomaterials can be regulated, and the composite can be used as a template to generate octahedral CdS-ZnS. Photocatalytic oxidation of toluene to benzaldehyde was used as a model reaction to evaluate the performance of the as-prepared samples, and the CZ-2 catalyst shows the highest photocatalytic activity, giving a benzaldehyde formation rate of 1078 mu mol.g(-1).h(-1) without the need of any solvent. The excellent performance is ascribed to the octahedral structure which is large in specific surface area and compact in heterojunctions. It is envisaged that the method is suitable for the generation of heterojunctions for photocatalytic purposes.

Background The side reactions of dehalogenation or C-N coupling tend to occur when halogenated aromatic amines are prepared by catalytic hydrogenation reduction of halogenated aromatic nitro compounds. In this paper, we prepared the sub-microspherical Fe3O4@PDA-Pd NPs catalyst apply it efficiently in the hydrogenation reduction of halogenated aromatic nitro compounds to prepare the halogenated aromatic amines under atmospheric pressure. The catalyst shows a high selectivity of greater than 96% and can effectively inhibit the occurrence of the side reactions of dehalogenation and C-N coupling. Results The optimum condition of the hydroreduction reaction is when tetrahydrofuran is used as solvent and the reaction happens at 50 degrees C for 5 h. The selectivity of the chlorinated aromatic amine and the fluorinated aromatic amine products exceed 99% and the yield exceeds 90%. Only a small amount of dehalogenated products and C-N coupling by-products were produced in the brominated aromatic compound and the iodinated aromatic compound. Conclusion We developed a promising method for preparing the superparamagnetic and strongly magnetic Fe3O4@PDA core-shell sub-microsphere-supported nano-palladium catalyst for catalyzing the hydrogenation reduction of halogenated aromatic nitro compounds. The halogenated aromatic amines were efficiently and highly selectively prepared under atmospheric pressure, with the side reactions of dehalogenation and C-N coupling effectively inhabited simultaneously.

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.

Recommanded Product: 50-84-0. The Name is 2,4-Dichlorobenzoic acid. Through research, I have a further understanding and discovery of 50-84-0.

Three kinds of novel hydroxyapatite@terbium complex core-shell composites were synthesized with 2-chlorobenzoic acid, 4-chlorobenzoic acid, and 2,4-dichlorobenzoic acid as the ligand, respectively. The XRD, UV/vis absorption and FT-IR results show that terbium ions are coordinated with ligands and the corresponding complexes are successfully included into composites. SEM and EDS results reveal that Tb complexes are fully and homogenously coated on the surface of hydroxyapatite (HAP) microspheres consisting of a large number of nanosized crystals. The strongest luminescence properties are obtained when 2,4-dichlorobenzoic acid is used as ligand. The study on fluorescence lifetime of composites shows that the lifetime is inversely related to emission intensity. TGA-DSC results indicate that the core-shell composites have an excellent thermal stability. Therefore, the current core-shell structure provides a cost-effective route to manufacture of biocompatible and heat-resistant highly luminescent materials. (C) 2020 Chinese Society of Rare Earths.

A strategy involving bimetallic catalysis with a combination of Cp*Co(CO)I-2 and Cu(OAc)(2) was used for performing Buchwald-type C-N coupling reactions of aryl chlorides with amines. The reactions proceeded at 100 degrees C to produce excellent yields of many of the desired C-N coupled products, in 4 h, under aerobic reaction conditions. The reactions were shown to run under base-free and solvent-free conditions, enabling this strategy to work efficiently for electron-withdrawing and base-sensitive functionalities. The presented methodology was found to be equally efficient for electron-donating functionalities as well as for primary (1 degrees) and secondary (2 degrees) aromatic and aliphatic amines. Moreover, the products were easily separated through the extractions of the organic aqueous layer, with this process chromatographic separations is not required.

In this study, we designed and synthesized a series of phthalazinone acridine derivatives as dual PARP and Topo inhibitors. MTF assays indicated that most of the compounds significantly inhibited multiple cancer cells proliferation. In addition, all the compounds displayed Topo II inhibition activity at 10 mol/L, and also possessed good PARP-1 inhibitory activities. Subsequent mechanistic studies showed that compound 9a induced remarkable apoptosis and caused prominent S cell cycle arrest in HCT116 cells. Our study suggested that 9a inhibiting Topo and PARP concurrently can be a potential lead compound for cancer therapy.

Background:Licensed therapies for nonalcoholic fatty liver disease (NAFLD) do not yet exist, but clinical trials are testing treatment options. Inclusion criteria often require liver biopsy showing fibrosis (F2/3) or cirrhosis (F4) and nonalcoholic steatohepatitis (NASH). However, histological criteria pose a serious obstacle for recruitment. Aims:Characterize the relevance of liver biopsies in the selection of patients with NAFLD. Methods:Patients between 2013 and 2018 with the ICD-10 code K76.0 were analyzed. Fibrosis was defined by the NASH clinical research network (CRN) fibrosis staging system, NASH by a NAFLD activity score (NAS) >= 4. Predictive factors were determined by logistic regression. Results:Liver biopsy was performed in 87/638 (13.6%) patients (49% female, age 52.5 +/- 14.0, BMI 30.4 +/- 5.9 kg/m(2)). Fibrosis stage F0/F1/F2/F3/F4 was observed inN = 7/47/7/17/9, an NAS >= 4 inN = 27. Fibrosis stage F2/F3 and F4 along with NAS >= 4 was found in 1.7% and 0.5% of cases. Liver stiffness measurement, LSM (OR 2.3 per doubling of value; CI 1.3-4.4,p = .005) and FIB-4 (OR 2.3 per doubling of value; CI 1.2-4.4,p = .012) were significant predictors for fibrosis >= F2. Predictive factors for NASH were not identified. Conclusion:The biopsy rate in NAFLD patients is low and fibrosis >= F2 along with NAS >= 4 only present in a few cases. Transient elastography and FIB-4 are useful to select patients at risk for fibrosis for liver biopsy.
