The highly strained [5](2,4)quinolinophane system can be generated as an intermediate (2b), which is extremely susceptible towards the attack of both nucleophilic and electrophilic species. Addition of water at the carbon bridgehead C2 occurs rapidly and is followed by rearrangements to give a strain free product 10. An unusual carbene addition at the N1C2 bond of 2b is proposed to explain the formation
高度紧张的[5](2,4)喹啉啉系统可以作为中间体(2b)生成,该中间体极易受到亲核和亲电子物种的攻击。在碳桥头C2上加水迅速发生,并且随后进行重排以得到无应变的产物10。有人提出在2b的N1C2键处添加不同寻常的卡宾,以解释形成应变的“抗-布雷德”型烯烃11的形成。
