The Tethered Counterion-Directed Catalysis (TCDC) approach has been applied to the enantioselective Au(I) catalyzed dearomatizations of 1-naphthols with allenamides. Stereocontrol is ensured by the intramolecular ion-pairing between the chiral gold-tethered phosphate and an iminium unit, that provides a rigid, well-defined chiral environment to the key electrophilic intermediate.
系留反离子导向催化 (TCDC) 方法已应用于对映选择性 Au( I ) 催化的 1-萘酚与烯丙酰胺的脱芳构化。立体控制由手性金系磷酸盐和亚胺单元之间的分子内离子对确保,为关键的亲电子中间体提供刚性、明确的手性环境。
