A palladium-catalyzed carboxylic acid-directed cross-coupling of an ortho-C(sp(2)) atom of aromatic acids with aliphatic aziridines to construct the beta-arylethylamine skeleton via C-H activation has been developed. The reaction proceeded under mild conditions with great substrate scope. Meanwhile, the beta-arylethylamine skeleton in drugs or bioactive compounds could be easily generated in a single step. A catalytic amount of cesium carbonate was crucial to realizing the selective beta-arylethylamine synthesis.

The direct C3 alkylation of indoles and oxindoles is a challenging transformation, and only a few direct methods exist. Utilizing the underexplored ability of triaryl boranes to mediate the heterolytic cleavage of alpha-nitrogen C-H bonds in amines, we have developed a catalytic approach for the direct C3 alkylation of a wide range of indoles and oxindoles using amine-based alkylating agents. We also employed this borane-catalyzed strategy in an alkylation-ring opening cascade.

Computed Properties of C8H10O2

A palladium-catalysed direct alkenation of electron rich arenes in the presence of K2S2O8 with an acetic acid/1,4-dioxane solvent combination has been developed. The 1,4-dioxane co-solvent dramatically influences the rate of reaction, giving selectively disubstituted alkenes, while the addition of acetylacetone ligands was shown to increase site selectivity for the alkenation of monofunctionalized arenes. The participation of these carbonyl ligands has been confirmed by ESI-MS studies, with some key in situ intermediates in the catalytic cycle identified. A variety of electron rich arenes and olefinic substrates can be utilised in the direct oxidative coupling to give disubstituted alkenes in moderate to good yields. (C) 2019 Elsevier Ltd.

Fluorine-containing compounds have been widely used in the fields of pharmaceuticals, agrochemicals and functional materials, mainly due to the well-known fluorine effect of the fluoroalkyl groups on the physical, chemical and biological properties of molecules. Tri- and difluoromethyl ethers play an important role in many medicinally compounds. Among various fluorinated moieties, ORf-containing groups have attracted much more attention very recently owing to the impressive conformational changes and maximal shifts in electron distribution brought by fluorine. The alpha-fluorine substitution of ethers shortens and strengthens the C-O bond and thus improves the in vivo oxidative stability of the ether moiety of a drug. Over the past few decades, there are some reliable ways on accessing trifluoromethyl ethers and difluomethyl ethers. Considering the importance of synthesis of monofluoromethoxy arenes and the substrate limitation (phenols or alcohols) of current state, a method was developed to access monofluoromethoxy arenes from aryl halides, arylboronic acids and arenes via a one-pot synthesis. Phenols can be prepared by the hydroxylation of aryl halides catalyzed by transition-metal complexes. In this work, a new strategy was envisioned a two-step sequence for the conversion of aryl halides to monofluoromethoxy arenes based on the palladium-catalyzed conversion of aryl phenols and in situ conversion of the resulting phenoxides with monofluoromethylating reagents. The investigation began with optimization of the conversion of 1-chloro-4-methoxy-benzene. The approach was achieved by using Pd-2(dba)(3) (2 mol%) as the catalyst under an inert atmosphere, di-tertbuty1(2′,4′,6′-triisopropyl-[1,1′-biphenyl]-2-yl)phosphane (8 mol%) as the ligand, KOH (1 equiv.) as the nucleophile, and 1,4-dioxane/H2O (V : V=5 : 3) as the solvent. Further monofluoromethylation used fluoromethyl iodide (2 equiv.) as the monofluoromethylating reagent and CH3CN as the co-solvent. Finally, the desired product was obtained in 82% yield. Therefore, this method was also applied to drugs, for example, Loratadine could be converted to the corresponding product (2o) in 53% yield and Fenofibrate, reacting to form the monofluoromethoxy arenes (2p) in modest yield. One-pot method to access aryl monofluoromethyl ethers from arylboronic acids and arenes were also under consideration and the yields were objective.

Cooperative bimetallic catalysis is a fundamental approach in modern synthetic chemistry. We report bimetallic cooperative catalysis for the direct decarbonylative heteroarylation of ubiquitous carboxylic acids via acyl C-O/C-H coupling. This novel catalytic system exploits the cooperative action of a copper catalyst and a palladium catalyst in decarbonylation, which enables highly chemoselective synthesis of important heterobiaryl motifs through the coupling of carboxylic acids with heteroarenes in the absence of prefunctionalization or directing groups. This cooperative decarbonylative method uses common carboxylic acids and shows a remarkably broad substrate scope (>70 examples), including late-stage modification of pharmaceuticals and streamlined synthesis of bioactive agents. Extensive mechanistic and computational studies were conducted to gain insight into the mechanism of the reaction. The key step involves intersection of the two catalytic cycles via transmetallation of the copper-aryl species with the palladium(II) intermediate generated by oxidative addition/decarbonylation.

A diverse range of ureas, N-acylureas, carbamates, and thiocarbamates has been synthesized in good to excellent yields by reacting N-acylbenzotriazoles individually with amines or amides or phenols or thiols in the presence of diphenylphosphoryl azide (DPPA) as a suitable azide donor in anhydrous toluene at 110 degrees C for 3-4 hours. In this route, DPPA was found to be a good alternative to trimethylsilyl azide and sodium azide for the azide donor in Curtius degradation. The high reaction yields, one-pot and metal-free conditions, straightforward nature, easy handling, use of readily available reagents, and in many cases avoidance of column chromatography are the notable features of the devised protocol.

The nickel-catalyzed intermolecular carboacylation of alkenes with amides and tetraarylborates is presented. Bicyclic alkenes are readily functionalized with a variety of N-benzoyl-N-phenylbenzamides and triarylboranes, which are generated in situ from the corresponding tetraarylborates, to synthesize ketone products in up to 91% yield. Preliminary mechanistic studies suggest that migratory insertion precedes transmetalation and that reductive elimination is the turnover-limiting step. These reactions occur with excellent chemoselectivity and diastereoselectivity in the absence of a directing/chelating group and further demonstrate amides as practical acyl electrophiles for alkene dicarbofunctionalization reactions.

A water-mediated MCR strategy has been developed for the synthesis of donor (D)-acceptor(A) type hydrazinyl thiazolyl coumarins (HTCs) (4) in excellent isolated yields (90-98%) from a three component reaction of aromatic aldehydes/ketones (1), thiosemicarbazide (2) and 3-(2-bromoacetyl)-2H-chromen-2-one (3) catalyzed by an environmentally compatible montmorillonite (MMT) K10 clay at RT for 20-40 min. The present MCR strategy has several advantages that include its wide-spread substrate scope, eco-compatibility, short reaction times and products that do not require chromatographic purification. Besides, the method is simple to perform, it is easy to construct C-N, C=N and C-S bonds in one pot and the reaction can be scaled up to a gram level. Moreover, the catalyst can be reused 7 times without significant change of activity. The photophysical properties of the synthesized D-A type HTCs are also studied and it was noticed that the fluorescence properties can be varied with the position of electron donating group on the aromatic ring of aldehyde/ketone of HTCs. Most of the compounds exhibited bright fluorescence in chloroform (1.0 x 10(-5) M) with emission maxima ranging from 409 to 511 nm and large Stokes shifts. Further, the HOMO and LUMO energy levels of the HTCs are found in the range from -5.65 eV to -5.22 eV and -2.67 eV to -2.17 eV, respectively, and in good agreement with the reported hole transporting materials.

A new series of 2,4-disubstituted-2-thiopyrimidines 6a-t, 9a, and 9b was efficiently designed and synthesized as antiangiogenic and cytotoxic agents. Compounds 6j, 6l, and 6d showed IC50 values of 1.23, 3.78, and 3.84 mu M, respectively, against the vascular endothelial growth factor receptor-2 (VEGFR-2). Most of the synthesized 2-thiouracils showed antiproliferative activity against the HepG2 cell line (hepatocellular carcinoma) in the micromolar range, for instance, 9b, 6l, 6m, 6n, and 6j displayed IC50 = 7.92, 8.35, 8.51, 9.59, and 13.06 mu M, respectively, relative to sorafenib (III; IC50 = 10.99 mu M). Also, compounds 6j, 9a, 6m, and 6s (IC50 = 15.21, 16.96, 17.68, and 18.15 mu M, respectively) are the most potent compounds against the UO-31 cell line. Further evaluation of the effect of the synthesized candidates on VEGFR-2 in the HepG2 cell line demonstrated that compounds 6j and 6l exhibit VEGFR-2 inhibitory activity of 87% and 84%, respectively, relative to sorafenib (III; 92%). In silico docking of the synthesized hits into the binding site of VEGFR-2 showed their ability to perform the main binding interactions with the key amino acids in the binding site. Studying the in silico predicted ADME (absorption, distribution, metabolism, and excretion) parameters for the synthesized thiouracils demonstrated that they have favorable pharmacokinetic and drug-likeness properties. These results demonstrate that the 2,4-disubstituted thiouracils 6 and 9 have not only favorable antiangiogenic and antiproliferative activity but also satisfy the criteria required for the development of orally bioavailable drugs. Consequently, they represent a biologically active scaffold that should be further optimized for future discovery of potential hits.
