The first total synthesis of the pyranoisoflavone kraussianone 1 (1) is described. The key steps involved the Suzuki−Miyaura reaction for the construction of the isoflavone core and the regioselective formation of the dimethylpyran scaffolds to the phloroglucinol (ring A) and resorcinol (ring B) moieties of kraussianone 1 (1). This route also provided access to the related isoflavones eriosemaone D
描述了吡喃异黄酮kraussianone 1(1)的第一个全合成。关键步骤涉及Suzuki-Miyaura反应,用于构建异黄酮核心以及二甲基吡喃骨架骨架选择性形成kraussianone 1(1)的间苯三酚(A环)和间苯二酚(B环)部分的区域。该途径还提供了通过简单的结构修饰获得相关异黄酮eriosemaone D(2)和染料木黄酮(3)的途径。
