Enone construction: A silver‐mediated olefin acylation reaction is described, in which five‐, six‐, and ‐seven‐membered rings, tetrasubstituted olefins, bridged bicycles, spirocycles, and benzoxepinones are prepared. Highly selective intermolecular reactions are coupled to a Nazarov cyclization for the effective preparation of cyclopentenones, including the core of modhephene (see scheme).
烯酮的结构:描述了一种银介导的烯烃酰化反应,其中制备了五元,六元和七元环,四取代的烯烃,桥连的自行车,螺环和苯并庚二酮。高度选择性的分子间反应与Nazarov环化反应相结合,可有效制备环戊烯酮,包括莫非芬的核心(参见方案)。
