Borate esters as convenient reagents for direct amidation of carboxylic acids and transamidation of primary amides.
Simple borates serve as effective promoters for amide bond formation with a variety of carboxylic acids and amines. With trimethyl or tris(2,2,2-trifluoroethyl) borate, amides are obtained in good to excellent yield and high purity after a simple work-up procedure. Tris(2,2,2-trifluoroethyl) borate can also be used for the straightforward conversion of primary amides to secondary amides via tra...
متن کاملReactivity and catalysis in reactions of the serine hydroxyl group and of O-acyl serines.
Certain acyl transfer and hydrolytic reactions catalyzed by chymotrypsin and related enzymes proceed with the formation of an isolable enzyme-substrate intermediate, in which the acyl portion of the substrate is covalently bound to the enzyme. A considerable body of evidence now exists which suggests that the site of enzyme acylation, as well as phosphorylat,ion, is the hydroxyl group of a seri...
متن کاملK2CO3-promoted formation of aryl esters from primary aryl amides by the acyl-acyl exchange process.
A new acyl-acyl exchange reaction has been developed for the formation of aryl esters from primary aryl amides. The reaction could occur under mild reaction conditions with catalytic quantities of K2CO3, and could afford moderate to good yields of the desired products.
متن کاملEvaluation of enoyl-acyl carrier protein reductase inhibitors as Pseudomonas aeruginosa quorum-quenching reagents.
Pseudomonas aeruginosa is an opportunistic pathogen which is responsible for a wide range of infections. Production of virulence factors and biofilm formation by P. aeruginosa are partly regulated by cell-to-cell communication quorum-sensing systems. Identification of quorum-quenching reagents which block the quorum-sensing process can facilitate development of novel treatment strategies for P....
متن کاملN-acyl glycinates as acyl donors in serine protease-catalyzed kinetic resolution of amines. Improvement of selectivity and reaction rate.
Enzymatic kinetic resolution of aliphatic and benzylic amines leading to (S)-amides was achieved by using alkaline protease as the catalyst and N-octanoyl glycine trifluoroethyl ester as the acyl donor; enantioselectivity ranged between 4 to 244, while reaction times were dramatically shortened and ranged between 15 min to 6 h.
