A practical and efficient synthesis of α-heteroaryl propionic esters is 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 is credited to the development of the bulky P,P═O ligand. The method has provided an efficient
通过使用钯催化的甲硅烷基乙烯酮缩醛的 α-杂芳基化,开发了一种实用且有效的 α-杂芳基丙酸酯合成方法,以高产率形成各种具有各种取代基和官能团的 α-杂芳基丙酸酯。这种转变的成功归功于庞大的 P,P=O 配体的开发。该方法提供了α-杂芳基丙酸的有效合成。
