stereoselective manner as a sequence involving two consecutive synergistic catalytic cycles (Lewis acid‐ and iminium ion‐catalyzed) and requires neither pre‐activated alkyl quinoline substrates with electron‐withdrawing substituents nor highly activated electrophiles. The reaction provides selectively double‐ or mono‐addition products in good yields and high to excellent stereoselectivities. Furthermore, based on
已开发出一种新的未活化烷基
喹啉的烷基官能化方法,以协同方式将InCl 3活化与α,β-不饱和醛的有机催化活化相结合。该反应以高度立体选择性的方式进行,涉及两个连续的协同催化循环(
路易斯酸和
亚胺离子催化),并且既不需要具有吸电子取代基的预活化烷基
喹啉底物,也不需要高度活化的亲电试剂。该反应以高收率和高至优异的立体选择性提供选择性的双或单加成产物。此外,基于光谱和标记实验,讨论了反应的机理。
