Rapid access to highly functionalized alkylidene cyclohexanols through a one-pot desymmetrizing hydroformylation/carbonyl ene cyclization starting from simple bisalkenylcarbinols is reported. Mechanistic insight into the carbonyl ene reaction is given, highlighting the importance of hyperconjugative substituent effects.
据报道,从简单的双烯基羰基化合物开始,通过一锅去对称化加氢甲酰化/羰基烯环化,可快速获得高度官能化的亚烷基
环己醇。给出了对羰基烯反应的机械学见解,突出了超共轭取代基作用的重要性。
