A palladium-catalyzed, ligand controlled regiodivergent semireduction of allenamides has been developed. This phosphine ligand-switched semireduction system has enabled an easy access to a broad scope of allylic and vinylic amides by using a single palladium catalyst. The excellent regio- and stereoselectivities of the divergent processes were achieved by the employment of monodentate Xphos and bidentate
已经开发了钯催化的、配体控制的烯丙酰胺的区域发散半还原。这种膦配体转换的半还原系统可以通过使用单一钯催化剂轻松获得广泛的烯丙酰胺和乙烯基酰胺。通过使用单齿 Xphos 和双齿 BINAP 配体(参见方案),可以实现不同过程的出色区域选择性和立体选择性。
