of naturally occurring kjellmanianone has been accomplished starting from tricyclo[5.2.1.02,6]decadienone 2-carboxylic ester . The key steps in this approach to include Barton's halodecarboxylation methodology, nucleophilic epoxidation to introduce the hydroxy group and ultimately, a cycloreversion by using flash vacuum thermolysis. The R configuration of synthetic (−)-kjellmanianone was unequivocally
从三环[5.2.1.0 2,6 ]癸二烯酮2-羧酸酯开始,完成了对自然存在的jjellmanianoneone的完全立体控制的全合成。该方法的关键步骤包括Barton的卤代羧化方法,亲核环氧化以引入羟基,并最终通过使用快速真空热解进行环还原。通过对其前体的X射线衍射分析明确地确定了合成(-)-kjellmanianone的R构型,这意味着需要修改以前分配的(+)-kjellmanianone的绝对构型。
