Catalytic amide formation from non-activated carboxylic acids and amines.
The amide functionality is found in a wide variety of biological and synthetic structures such as proteins, polymers, pesticides and pharmaceuticals. Due to the fact that synthetic amides are still mainly produced by the aid of coupling reagents with poor atom-economy, the direct catalytic formation of amides from carboxylic acids and amines has become a field of emerging importance. A general,...
متن کاملNew catalytic transformations of carboxylic acids*
A series of metal-catalyzed processes are presented, in which carboxylic acids act as sources of either carbon nucleophiles or electrophiles, depending on the catalyst employed, the mode of activation, and the reaction conditions. A first reaction mode is the addition of carboxylic acids or amides over C–C multiple bonds, giving rise to enol esters or enamides, respectively. The challenge here ...
متن کاملCatalytic reductive N-alkylation of amines using carboxylic acids.
We report a catalytic reductive alkylation reaction of primary or secondary amines with carboxylic acids. The two-phase process involves silane mediated direct amidation followed by catalytic reduction.
متن کاملMid-chain carboxylic acids by catalytic refining of microalgae oil
Microalgae oil serves as a feedstock for a biorefinery approach to mid-chain (di-)carboxylic acid esters, currently only accessible via demanding synthetic routes. Via the butenolysis of monoand poly-unsaturated fatty acids, short-chain unsaturated fatty acid methyl esters and monoand di-enes were produced in a high selectivity. These olefins were further processed into value added linear mid-c...
متن کاملToward Catalytic, Enantioselective Chlorolactonization of 1,2-Disubstituted Styrenyl Carboxylic Acids
An investigation into the use of Lewis base catalysis for the enantioselective chlorolactonization of 1,2-disubstituted alkenoic acids is described. Two mechanistically distinct reaction pathways for catalytic chlorolactonization have been identified. Mechanistic investigation revealed that tertiary amines predominately operate as Brønsted rather than Lewis bases. Two potential modes of activat...
