A phosphine-catalyzed [4 + 3] annulation of modified allylic carbonates with methyl coumalate was developed. This strategy offered a powerful method for the construction of bicyclo[3.2.2]nonadiene skeleton with high stereoselectivity.
开发了膦用
香豆酸甲酯催化的[4 + 3]改性烯
丙基碳酸酯的环化反应。该策略为构建具有高立体选择性的双环[3.2.2]壬二烯骨架提供了有力的方法。
