Author is Zhu, Jun; Chen, Peng-hao; Lu, Gang; Liu, Peng; Dong, Guangbin.

Cleavage of carbon-carbon bonds has been found in some important industrial processes, e.g. petroleum cracking, and has inspired development of numerous synthetic methods. However, non-polar unstrained C(aryl)-C(aryl) bonds remain one of the toughest bonds to be activated. As a detailed study of a fundamental reaction mode, here a full story is described about the development of a Ru-catalyzed reductive cleavage of unstrained C(aryl)-C(aryl) bonds. A wide range of biaryl compounds that contain directing groups (DGs) at 2,2′ positions can serve as effective substrates. Various heterocycles, such as pyridine, quinoline, pyrimidine and pyrazole, can be employed as DGs. Besides hydrogen gas, other reagents, such as Hantzsch ester, silanes and alcs., can be employed as terminal reductants. The reaction is pH neutral and free of oxidants, thus a number of functional groups are tolerated. Notably, a one-pot C-C activation/C-C coupling has been realized. Computational and exptl. mechanistic studies indicate that the reaction involves a ruthenium(II) monohydride-mediated C(aryl)-C(aryl) activation and the resting state of the catalyst is a η4-coordinated ruthenium(II) dichloride complex, which could inspire development other transformations based on this reaction mode.

Author is Lin, Runfeng; Zhang, Zheng; Cao, Shengtian; Yang, Wen; Zuo, Yinglin; Yang, Xinye; Zhang, Jiancun; Xu, Juan; Li, Jing; Wang, Xiaojun.

Idiopathic pulmonary fibrosis (IPF) is a chronic progressive lung disease with a typical survival time between three to five years. Two drugs, pirfenidone and nintedanib have been approved for the treatment of IPF, but they have limited efficacy. Thus, the development of new drugs to treat IPF is an urgent medical need. In this paper we report the discovery of a series of orally active pyrimidin-4(3H)-one analogs which exhibit potent activity in in vitro assays. Among them, HEC-866 showed promising efficacy in rat IPF models. Since HEC-866 also had good oral bioavailability, a long half-life and favorable long-term safety profiles, it was selected for further clin. evaluation.

Compound: 1-(2-Bromophenyl)-1H-pyrazole, is researched, Molecular C9H7BrN2, CAS is 87488-84-4, about Hypercrosslinked Polymer Platform-Anchored Single-Site Heterogeneous Pd-NHC Catalysts for Diverse C-H Functionalization, the main research direction is hypercrosslinked polymer anchored palladium carbene complex preparation catalyst halogenation; arene acetylation hypercrosslinked polymer anchored palladium carbene catalyst; heteroarene arylation hypercrosslinked polymer anchored palladium carbene catalyst.COA of Formula: C9H7BrN2.

The authors demonstrate a new class of hypercrosslinked polymer (HCP) platform-anchored single-site heterogenized Pd-NHC catalysts for multipurpose C-H functionalization reactions. This new class is represented by a set of three catalysts, viz., HCP-B-MeNHC-Pd, HCP-B-BnNHC-Pd, and HCP-TPM-MeNHC-Pd, having a variation on the structural feature of the anchoring polymeric platform. All three catalysts were fully characterized via diverse solid-state characterization and anal. techniques such as XPS, 13C CPMAS NMR, field-emission SEM, energy-dispersive x-ray anal., TGA, and inductively coupled plasma-optical emission spectrometry. Three types of regularly practiced and very useful C-H functionalization reactions, viz., C-H halogenation, acetoxylation, and arylation, are tested with the new catalysts and are highly compatible and successful. With the HCP-TPM-MeNHC-Pd catalyst, up to 85, 75, and 70% yields of the functionalized products were achieved for the halogenation, acetoxylation, and arylation reactions, resp. Demanding attributes such as enhanced activity, heterogeneity, and recyclability are offered by this new system, making it a promising candidate in the field of heterogeneous C-H functionalization, where only a few efficient catalysts are available.

A series of six carbonylrhodium(I) complexes of three new and three previously reported di((2-3R-pyrazolyl)-p-Z/X-aryl)amido pincer ligands, (RZX)Rh(CO), (R is the substituent at the 3-pyrazolyl position proximal to the metal; Z and X are the aryl substituents para- to the arylamido nitrogen) were prepared The metal complexes were studied to assess how their properties and reactivities can be tuned by varying the groups along the ligand periphery and how they compared to other known carbonylrhodium(I) pincer derivatives This study was facilitated by the discovery of a new CuI-catalyzed coupling reaction between 2-(pyrazolyl)-4-X-anilines (X = Me or CF3) and 2-bromoaryl-1H-pyrazoles that allow the fabrication of pincer ligands with two different aryl arms. The NNN-pincer scaffolds provide an electron-rich environment for the carbonylrhodium(I) fragment as indicated by carbonyl stretching frequencies that occur in the range of 1948-1968 cm-1. As such, the oxidative addition (OA) reactions with iodomethane proceed instantaneously to form trans-(NNN-pincer)Rh(Me)(CO)(I) in room temperature acetone solution The OA reactions with iodoethane proceeded at a convenient rate in acetone near 45° which allowed detailed kinetic studies. The relative order of reactivity was (CF3CF3)Rh(CO) < (iPrMeMe)Rh(CO) < (MeMeMe)Rh(CO) ∼ (CF3Me)Rh(CO) < (MeH)Rh(CO) < (MeMe)Rh(CO) with the second order rate constant of the most reactive in the series, k 2 = 8 × 10-3 M-1 s-1, being about three orders of magnitude greater than those reported for [Rh(CO)2I2]- or CpRh(CO)(PPh3). After oxidative addition, the resultant rhodium(III) complexes were unstable. Although a few trans-(RMeMe)Rh(E = Me, Et, or I)(CO)(I) could be isolated in pure form, all were found to slowly decompose in solution to give different products depending on the 3R-pyrazolyl substituents. Those with unsubstituted pyrazolyls (R = H) decompose with CO dissociation to give insoluble dimeric [(RMeMe)Rh(E)(μ-I)]2 while those with 3-alkylpyrazolyls (R = Me, iPr) decompose to give soluble, but unidentified products.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

Thrombosis is a pathol. coagulation process and can lead to many serious thrombotic diseases. Here, we report a novel potent antithrombotic compound (6k) based on isosteviol with anticoagulant and antiplatelet activities. 6k selectively inhibited FXa (Ki = 0.015μM) against a panel of serine proteases and showed excellent anticoagulant activity (significant prolongation of ex vivo PT and aPTT over the vehicle, p < 0.01). 6k also significantly inhibited ADP-induced platelet aggregation in rats relative to the vehicle (p < 0.01). Furthermore, 6k exhibited potent ex vivo and in vivo antithrombotic activity in rats relative to the vehicle (p < 0.01 and p < 0.0001, resp.). Novel structure 6k, with potent antithrombotic activity, is expected to lead a promising approach for the development of antithrombotic agents.
