Advances in Ligand‐Driven Pd‐Catalyzed C─H Functionalizations: Recent Insights and Updates
The most significant advances in ligand‐driven Pd‐catalyzed organic synthesis over the past two years are presented. Processes involving C─H activation of substrates, avoiding their prefunctionalization are illustrated. Both the activity and selectivity of the catalyst depend on the design of the ligands (pyridones, pyridines, amino acids, phosphines ...

Synthesis of α-aminophosphonates by the Kabachnik–Fields reaction and by the Pudovik reaction [PDF]
α-Aminophosphonates are of significant importance due to their biological activity. The most widely applied synthetic routes towards α-aminophosphonates are the Kabachnik-Fields reaction involving the condensation of amines, oxo compounds and >P(O)H ...

The serine capsid protease (CP) catalyzes a crucial process of the alphaviral replication cycle; therefore, it constitutes an interesting therapy target. Herein, the O'nyong‐nyong virus CP profile activity with a specific fluorogenic substrate is analyzed and examines the inhibitory activity of a new series of phosphonic analogs of tryptophan and ...

Syntheses of quinoline and quinoxaline derivatives fused with phosphacycles were developed from commercially available quinolin‐6‐amine and quinoxalin‐6‐amine. Abstract Despite their potential in areas such as medicinal chemistry and organic materials, scaffolds in which quinoline and quinoxaline are fused to phosphacycles such as 1,3‐oxaphosphole, 1,3‐
