salt-activated, Pd-catalyzed Suzuki–Miyaura and Sonogashira cross-coupling reactions of cyclic 1,3-diones in the synthesis of β-substituted cyclic enones are described. These transformations exhibit good isolated yield and high generality with respect to both substrates and coupling partners. Extension of the substrate scope to cyclic 1,3-dione equivalents, such as 2-cyanocyclohexanone (4), is also briefly examined
描述了在合成β-取代的环状烯酮时,环状1,3-二酮的salt盐活化,Pd催化的Suzuki-Miyaura和Sonogashira交叉偶联反应。这些转化相对于底物和偶联伴侣表现出良好的分离产率和高通用性。还简要地研究了将底物范围扩展至环状1,3-二酮等同物,例如2-氰基环己酮(4)。
