(-)-N,N-Dimethylaminoisoborneol ((-)-DAIB) was found to be an excellent ligand for the enantioselective addition of Reformatsky reagents to aromatic and aliphatic aldehydes. Enantioselectivities up to 93% ee were obtained with sulfur-containing aldehydes.
(-)-N,N-二甲基氨基异薄荷醇 ((-)-DAIB) 被发现是一种非常适合用于芳香族和脂肪族醛与Reformatsky 试剂进行手性选择性加成的配体。使用含硫的醛类时,获得了高达93% ee的手性选择性效果。
