In the paper we indicate the increasing importance of derivatives containing a dihydropyrrolo[1,2-b]pyrazole (DPP) core. We try to show our synthetic approach based on an improved Kulinkovich method as well as our new synthetic pathway. A complex methodology involving the preparation of substituted DPPs focuses on withasomnine and the synthesis of several structurally related compounds. The developed
在本文中,我们表明了含有二氢吡咯并[1,2- b]吡唑(DPP)核心。我们尝试展示基于改进的Kulinkovich方法以及新的合成途径的合成方法。涉及取代DPPs制备的复杂方法论着重于asasomnine和几种结构相关化合物的合成。发达的反应方案能够制备具有广泛不同取代基的上述双环系统。因此,我们能够制备具有脂族,芳族,聚芳族,杂芳族,TMS甚至金刚烷取代基且具有已知生物活性的系统。该反应方案由两个多步骤的合成途径组成,包括Sonogashira和Suzuki-Miyaura交叉偶联反应,烯基合成子形成,Kulinkovich环丙烷化,环转化和不对称的同烯丙基烯丙基环加成环。
