In the presence of [Ir(cod)Cl}2] and a binol‐derived phosphoramidite ligand, spirocyclohexadienone derivatives were obtained with up to 97 % ee through iridium‐catalyzed intramolecular asymmetric allylic dearomatization of phenols (see scheme; cod=cycloocta‐1,5‐diene).
失去芳香性:在[Ir(cod)Cl} 2 ]和由多元醇衍生的亚磷酰胺配体的存在下,通过铱催化的分子内酚类不对称烯丙基芳构脱芳香化反应,可以得到螺环己二酮衍生物的最高97% ee(参见方案; cod = cycloocta-1,5-diene)。
