QuinoxP*: A Privileged Ligand in Asymmetric Transition‐Metal Catalysis

QuinoxP*, characterized by a quinoxaline backbone bearing two P‐stereogenic phosphine units, demonstrates excellent activity and stereoselectivity in asymmetric transition‐metal catalysis. Since its initial synthesis in 2005, and especially over the past decade, there has been a notable increase in studies reporting its application in transition‐metal‐catalyzed asymmetric transformations. Despite this expanding body of literature, a comprehensive review dedicated to this privileged ligand remains absent. To address this gap, the present review provides a thorough overview of the origin of QuinoxP* and its structural features and key properties, as well as its diverse catalytic applications in the past decade. Furthermore, we examine its current limitations and discuss future directions for the advancement and utilization of this remarkable ligand.
