Li, Bowen;Luo, Bangke;Blakemore, Caroline A.;Smith, Aaron C.;Widlicka, Daniel W.;Berritt, Simon;Tang, Wenjun research published 《 Synthesis of α-Heteroaryl Propionic Esters by Palladium-Catalyzed α-Heteroarylation of Silyl Ketene Acetals》, the research content is summarized as follows. A practical and efficient synthesis of α-heteroaryl propionic esters was developed by employing palladium-catalyzed α-heteroarylation of silyl ketene acetals, forming a wide variety of α-heteroaryl propionic esters with various substituents and functionalities in high yields. The success of this transformation was credited to the development of the bulky P,P=O ligand. This method provided an efficient synthesis of α-heteroaryl propionic acids.
