A novel class of achiral templates containing fluxional groups has been evaluated in conjugate radical additions. Magnesium and copper Lewis acids provide high enantioselectivity (>90% ee) for radical additions. The impact of the metal geometry on enantioselectivity using relay templates has also been assessed.
一种包含可变基团的新型无手性模板已在共轭自由基加成反应中进行了评估。
镁和
铜路易斯酸在自由基加成中提供了高的对映体选择性(>90% ee)。还评估了
金属几何形状对使用中继模板的对映体选择性的影响。
