In Situ Formation of Cationic π-Allylpalladium Precatalysts in Alcoholic Solvents: Application to C-N Bond Formation

We report an efficient Buchwald-Hartwig cross-coupling reaction in alcoholic solvent, in which a low catalyst loading showed excellent performance for coupling aryl halides (I, Br, and Cl) with a broad set of amines, amides, ureas, and carbamates under mild conditions. Mechanistically speaking, in a protic and polar medium, extremely bulky biarylphosphine ligands interact with the dimeric precatalyst [Pd(π-(R)-allyl)Cl]2 to form the corresponding cationic complexes [Pd(π-(R)-allyl)(L)]Cl in situ and spontaneously. The resulting precatalyst further evolves under basic conditions into the corresponding L-Pd(0) catalyst, which is commonly employed for cross-coupling reactions. This mechanistic study highlights the prominent role of alcoholic solvents for the formation of the active catalyst.

Method for synthesizing amide compound through photocatalysis in water phase

The invention discloses a method for synthesizing an amide compound through photocatalysis in a water phase. The method comprises the following steps: putting catalysis amounts of a free radical initiator, an amine derivative, a carboxylic acid derivative, a phase transfer catalyst, an inorganic base and water into a reaction container, carrying out a reaction in a photocatalysis reaction instrument at certain power under a room temperature condition, after a certain time, carrying out extraction by using a small amount of ethyl acetate, and carrying out recrystallization, so as to obtain theamide compound, wherein the free radical initiator is eosin, methyl orange, sodium persulfate, ammonium persulfate or potassium peroxodisulfate, the phase transfer catalyst is tetrabutylammonium bromide, and the power of the photocatalytic reaction instrument is 5W. By adopting the method disclosed by the invention, toxic thionyl chloride or phosphorus oxychloride is not needed for a chlorinationreaction, water is adopted as a solvent, a novel photocatalysis method is used, and the amide compound with a high yield can be prepared through a room-temperature reaction for 2-5 hours with an incandescent light bulb of 5W, and in addition, the method is simple in aftertreatment, and low in cost and is an ideal green synthesis method of amide compounds.

Efficient and Mild Ullmann-Type N-Arylation of Amides, Carbamates, and Azoles in Water

A simple, sustainable, efficient, mild, and low-cost protocol was developed for d-glucose-assisted Cu-catalyzed Ullmann reactions in water for amides, carbamates, and nitrogen-containing heterocycles. The reaction was compatible with diverse aryl/heteroaryl iodides, giving highly substituted pyridine, indole, or indazole rings. This method offers an attractive alternative to existing protocols, because the reaction proceeds in aqueous media, occurs at or near ambient temperature, and provides the N-arylated products in good to high yields.

NOVEL BIARYLAMIDE DERIVATIVE AND COMPOSITIONS CONTAINING THE DERIVATIVE AS AN ACTIVE INGREDIENT

The present invention relates to a novel biarylamide derivative and a pharmaceutical composition or a cosmetic composition comprising the same as an active ingredient. More particularly, the present invention relates to a novel biarylamide derivative, a pharmaceutical composition or a cosmetic composition for preventing or treating a pigmentation disorder caused by an abnormal excess of melanin or a disease caused by melanocyte hyperplasia comprising the same as an active ingredient. The biarylamide derivative of the present invention inhibits melanin production and thus inhibits melanocyte hyperplasia. Therefore, a cosmetic composition comprising the biarylamide is excellent in a whitening effect, and a pharmaceutical composition comprising the biarylamide is effective in the prevention or treatment of pigmentation disorders of skin such as lentigo, melasma, freckle, etc. and malignant melanoma.

On the basis of a hit from random screening, biaryl amide derivatives were prepared in a combinatorial manner via parallel solution-phase synthesis, and their effects on melanocytes were investigated to discover new effective skin depigmenting agents. Amo

Iron-catalyzed N-arylations of amides

A method was proposed for iron-catalyzed N-arylation of primary amides and its applicability to the synthesis of N-heterocycles by intramolecular ring closures. The method used a catalyst system of 10 mol % of FeCl3 and 20 mol % of N,N'-dimethylethylenediamine (DMEDA). The study found that secondary amides of N-methylbenzamide and N-benzylbenzamide produce N-arylated products in trace amounts. The method developed an iron-based catalyst system for efficient N-arylations of primary amides with aryl iodides. The study used a sealable tube equipped with a magnetic stir bar charged with amide, or K 3PO4, or K2CO3, or FeCl3. The study used NMR spectroscopic analysis to determine the identity and purity of the products. The method observed that different substituted aryl iodides made a positive impact on the reaction.

Anticonvulsant activity of some 4-methoxy- and 4-chlorobenzanilides

A series of mono-, di-, and trimethylated derivatives of 4-chloro- and 4-methoxybenzanilide was synthesized and evaluated for anticonvulsant activity. This series was prepared in the course of studies designed to examine the relationship between anticonvulsant effects and benzamide structure. The compounds were tested in mice against seizures induced by maximal electroshock (MES) and pentylenetetrazole (scMet), as well as with the rotorod assay for neurologic deficit. In mice dosed intraperitoneally, 4-methoxy-2, 6-dimethylbenzanilide (4) showed a median anticonvulsant potency (ED50) of 18.58 mg/kg in the MES test and a median toxicity (TD50) of 133.72 mg/kg in the rotorod toxicity assay, yielding a protective index (PI = TD50/ED50) of 7.2. In mice dosed orally with 4, the anti-MES ED50 was 27.40 mg/kg and the TD50 dose was determined to be 342.58 mg/kg, resulting in a protective index of 12.5.
