metal-free one-pot two-step reductive coupling reaction of benzocyclonone, tosylhydrazide, and arylboronic acid was developed for the formation of a C(sp3)-C(sp2) bond, which enabled the efficient synthesis of 1-aryl-benzocycloalkane compounds in moderate to good yields on a multi-gram scale. Moreover, five- and six-membered benzocyclic ketones are also suitable substrates for this reaction. Notably
摘要 开发了苯环酮、甲苯磺酰肼和芳基硼酸的无金属一锅两步还原偶联反应形成 C(sp3)-C(sp2) 键,从而有效合成 1-芳基-在多克规模上以中等至良好的产率获得苯并环烷烃化合物。此外,五元和六元苯并环酮也是该反应的合适底物。值得注意的是, 该协议还被发现适用于合成 3-(3,4-二氯苯基)-2,3-二氢-1H-inden-1-one, 这是合成茚达林的重要中间体。图形概要
