An efficient Rh(III)-catalyzed Csp(2)-H amination protocol of benzoic acids with anthranils was developed for the rapid assembly of valuable anthranilic acid derivatives (AAs). The weakly coordinating carboxyl acted as a directing group and was further transformed to an ester group after facilitating the first C-H amination process. This reaction features good functional group tolerance, mild conditions and operational simplicity. The synthetic potential of this methodology was demonstrated by the synthesis of various useful heterocycles and derivatives.

Photoexcited electron-hole pairs on a semiconductor surface can engage in redox reactions with two different substrates. Similar to conventional electrosynthesis, the primary redox intermediates afford only separate oxidized and reduced products or, more rarely, combine to one addition product. Here, we report that a stable organic semiconductor material, mesoporous graphitic carbon nitride (mpg-CN), can act as a visible-light photoredox catalyst to orchestrate oxidative and reductive interfacial electron transfers to two different substrates in a two-or three-component system for direct twofold carbon-hydrogen functionalization of arenes and heteroarenes. The mpg-CN catalyst tolerates reactive radicals and strong nucleophiles, is straightforwardly recoverable by simple centrifugation of reaction mixtures, and is reusable for at least four catalytic transformations with conserved activity.

Category: isothiazole

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.

A protocol of highly regio- and enantioselective copper-catalyzed hydroacylation of the non-terminal CC bond in 1,1-disubstituted terminal allenes with anhydrides has been developed. Both aromatic and aliphatic carboxylic anhydrides are applicable to the efficient construction of all carbon quarternary centers connected with a versatile C-C bond and a useful ketone functionality. The synthetic potentials of the enantioenriched products have also been demonstrated. Density functional theory (DFT) calculations were performed to explain the steric outcome of the products: the hydroacylation proceeds through a six-membered transition state and the ligand-substrate steric interactions account for the observed enantioselectivity although the chiral ligand is far away from the to-be-genetated chiral center.

An efficient method for the directing group controlled rhodium-catalyzed addition reaction of oxa/azabicylic alkenes with aromatic ketones and benzoic acids has been developed. The ketones and benzoic acids afforded different addition products when reacted with oxa/azabicyclic alkenes. The reaction between ketones and azabenzonorbornadienes furnished the ring-opening addition products. The reaction between benzoic acids and aza/oxabicyclic alkenes proceeded in the absence of silver salt, giving the 1:2 hydroarylation products in yields up to 96%.

In addition, the compounds were screened for in vitro biological activity, and the bioassay results indicated that the newly synthesized compounds showed different in vitro antifungal activities against five plant fungi. Particularly, compound F-3 (EC50 = 11.16 mg/L) was found to be the most active respectively against Wheat gibberellic, even more effective than Fluconazole (EC50 = 16.03 mg/L). The active compounds were further evaluated for enzyme inhibition efficacy against the receptor CYP51 by docking. Meanwhile, an explicit surface analysis on compounds were carried out theoretically using the wave function analyzer (Multiwfn 3.4.1 software) in order to study the reactivity of the compounds.

The antifungal activity of a library of twenty-four aromatic methoximes was examined against five representative postharvest phytopathogenic fungi. The panel included Penicillium digitatum, Penicillium italicum, Rhizopus stolonifer, Botrytis cinerea and Monilinia fructicola, all of which cause relevant economic losses worldwide as a result of affecting harvested fruits. The minimum inhibitory concentrations and minimum fungicidal concentrations of each compound were defined and the main structure-activity relationships were determined. Although other congeners were more potent, drug likeliness considerations pointed to the methoxime derived from 2,4-dihydroxypropiophenone as the compound with the most suitable profile. The morphology of the colonies of the fungal strains treated with the methoxime was examined microscopically and the compound was also tested in freshly harvested peaches and oranges, exhibiting promising control profiles in both fruits, similar to those of the commercial agents Imazalil and Carbendazim.

A two-step one pot, experimentally simple protocol, based on readily available and inexpensive reagents allowed the conversion of nitro-arenes directly to N-aryl amides. A metal-free reduction of the nitro group, mediated by trichlorosilane, followed by the addition of an anhydride afforded the corresponding N-aryl carboxyamide, that was isolated after a simple aqueous work up in good-excellent yields. When the methodology was applied to the reaction with gamma-butyrolactone, the desired N-aryl butanamide derivative was obtained, featuring a chlorine atom at the gamma-position, a functionalized handle that can be used for further synthetic manipulation of the reaction product. Such an intermediate has already been employed as a key advanced precursor of pharmaceutically active compounds.
