Dual Effects of Cyclopentadienyl Ligands on Rh(III)-Catalyzed Dehydrogenative Arylation of Electron-Rich Alkenes

Despite extensive research on transition metal-catalyzed Fujiwara-Moritani type C-H olefinations, the alkenes used in these transformations are still mainly limited to active acrylate esters and styrenes. Selective aryl C-H olefination with electron-rich alkenes is recognized as a challenging issue. We herein report that simple and readily accessible electron-deficient [CpRh(III)] and [CpCF3Rh(III)] (CpCF3 = C5Me4CF3) complexes are powerful catalysts for dehydrogenative arylation of electron-rich alkenes, including vinyl acetates, enamides, and vinyl ethers. Employing an electron-withdrawing Cp or CpCF3 ligand instead of the privileged Cp? (C5Me5) ligand not only can facilitate the electrophilic aryl C-H rhodation but also can lower the olefin insertion barrier. Both electron-withdrawing and electron-donating directing groups such as -CONR2 and -NHAc could be employed in these reactions, which provides convenient routes toward a series styryl acetates, N-acetylindoles, and aryl methyl ketones.

Auto-tandem PET and EnT photocatalysis by crude chlorophyll under visible light towards the oxidative functionalization of indoles

Chlorophyll is the most abundant photocatalytic pigment that enables plants to absorb solar energy and convert it to energy storage molecules. Herein, we report a tandem photocatalytic approach utilizing the natural pigment chlorophyll in crude form to achieve photoinduced electron transfer (PET) and energy transfer (EnT) towards the oxidative functionalization of indoles. Redox potentials, ESR, fluorescence quenching and UV experiments have evidenced the dual catalytic activity of chlorophyll. The highlight of the study is the auto-tandem photocatalytic role of chlorophyll to enable the green oxidation of indoles using molecular oxygen as the oxidant, water as the reaction medium, and photochemical energy from the visible region of the spectrum.

2-aryl-2,3-dihydro-4(1H)-quinolinone semicarbazone compound and application thereof

The invention relates to the field of medicine technology, and a series of novel 2-aryl-2,3-dihydrogen-4(1H)-quinolinone semicarbazone derivatives (I) and pharmaceutically acceptable salts, solvates,optical isomers or polymorphs are designed and synthesized. The derivative (I) and its pharmaceutically acceptable salt, solvate, optical isomer or polymorph can be mixed as an active ingredient witha pharmaceutically acceptable carrier to prepare a pharmaceutical composition. A double dilution method is used for test of the antifungal activity of the derivative (I) and its pharmaceutically acceptable salt, solvate, optical isomer or polymorph, and the results show that the derivative has stronger killing effect on clinically common pathogenic fungi, and is expected to overcome the defects oflarge toxic and side effects, easy generation of drug resistance of azole antifungal medicines which are widely used clinically. The specific formula is shown in the description.
