Metal‐templated organocatalysis: The enantioselective formation of an all‐carbon quaternary stereocenter is catalyzed by the ligand sphere of an inert bis‐cyclometalated iridium complex (see picture). In this complex, the metal‐centered chirality serves as the sole source for the effective asymmetric induction.
金属为模板的有机催化:全碳四元立体中心的对映选择性形成是由惰性双环金属化铱配合物的配体球形催化的(见图)。在这种复合物中,以金属为中心的手性是有效非对称感应的唯一来源。
