A Photochemical Protocol for the Synthesis of Weinreb and Morpholine Amides from Carboxylic Acids
نویسندگان
چکیده
The Cover Feature illustrates the photochemical conversion of carboxylic acids to Weinreb and morpholine amides. Sunlight or LED 370 nm irradiation mediates direct coupling N,O-dimethylhydroxylamine in presence 4-dimethylaminopyridine bromotrichloromethane, providing corresponding amides satisfactory high yields.

Ultrasound-Promoted Synthesis of Aryl Amides from Isocyanides and Carboxylic Acids under Ambient Conditions
The synthesis of aryl amides via the reactions of carboxylic acids and isocyanides in methanol was carried out in 78-95% yields under ultrasound irradiation. The method has wide applicability, and the protocol is mild, fast and efficient compared to the existing methods based on silent conditions.

متن کاملDirect Synthesis of Amides from Carboxylic Acids and Amines Using B(OCH2CF3)3
B(OCH2CF3)3, prepared from readily available B2O3 and 2,2,2-trifluoroethanol, is as an effective reagent for the direct amidation of a variety of carboxylic acids with a broad range of amines. In most cases, the amide products can be purified by a simple filtration procedure using commercially available resins, with no need for aqueous workup or chromatography. The amidation of N-protected amin...
