The development of an enantioselective catalytic Claisen rearrangement remains an important yet elusive goal in chemical synthesis. With this objective in mind, we recently reported the acyl-Claisen rearrangement, a Lewis acid-catalyzed variant of the Bellus reaction that utilizes acid chlorides and allylic amines in the stereoselective synthesis of ɑ,β-disubstituted-y,δ-unsaturated carbonyls (eq 1)
对映选择性催化克莱森重排的发展仍然是化学合成中一个重要但难以实现的目标。考虑到这一目标,我们最近报道了酰基-克莱森重排,这是一种路易斯酸催化的 Bellus 反应变体,它利用酰氯和烯丙胺立体选择性合成 ɑ,β-二取代-y,δ-不饱和羰基(等式 1)。
