A new approach to synthesize cannabilactones using Suzuki cross-coupling reaction followed by one-step demethylation-cyclization is presented. The two key cannabilactone prototypes AM1710 and AM1714 were obtained selectively in high overall yields and in a lesser number of synthetic steps when compared to our earlier synthesis. The new approach expedited the synthesis of cannabilactone analogs with structural modifications at the four potential pharmacophoric regions.
使用Suzuki交叉偶联反应后跟一步脱甲基环化合成卡纳比拉克酮的新方法被提出。与我们之前的合成相比,两种关键的卡纳比拉克酮原型AM1710和AM1714以更高的总收率和更少的合成步骤被选择性地获得。这种新方法加速了在四个潜在的药效团区域进行结构修改的卡纳比拉克酮类似物的合成。
