An unprecedented remote effect of the hydroxyl group on π-facial selectivity was observed in the addition of Grignard reagents to bicyclo[2.2.2]octan-2-ones, where nucleophilic attack occured from the slerically more hindered face.
在双环[2.2.2] octan-2-ones中添加
格氏试剂后,观察到羟基对π面选择性的前所未有的遥远影响,亲核性攻击是由受阻较严重的面部发生的。
