Intermolecular oxidative cross‐coupling of two different enolates is one of the most useful reactions to synthesize unsymmetrical 1,4‐dicarbonyl compounds. In this study, the oxovanadium(V)‐induced intermolecular oxidative cross‐coupling of enolates afforded unsymmetrical 1,4‐dicarbonyl compounds. Various boron and silyl enolates underwent the formation of ketone–ester, ester–ketone, ester–ester, amide–ketone
两种不同烯醇的分子间氧化交叉偶联是合成不对称1,4-二羰基化合物的最有用的反应之一。在这项研究中,氧钒(V)诱导的烯醇盐的分子间氧化交叉偶联提供了不对称的1,4-二羰基化合物。各种硼和甲硅烷基烯醇盐经历了酮-酯,酯-酮,酯-酯,酰胺-酮和酰胺-酯偶联产物的形成。这些结果清楚地表明了本氧化交叉偶联方案的多功能性。
