The allylation reaction of aldimines with allyl metal reagents is an important synthetic method for the preparation of homoallylamines. Therefore, we wish to report a highly regioselective and stereoselective allylation reaction under sonochemical Barbier-type reaction conditions. The high yields of regioselective α-adducts were achieved by reacting cinnamyl bromide, zinc, 1,2-dibromoethane, and aldimine
醛亚胺与烯丙基金属试剂的烯丙基化反应是制备高烯丙胺的重要合成方法。因此,我们希望报道在声化学Barbier型反应条件下的高度区域选择性和立体选择性烯丙基化反应。通过使肉桂基溴、锌、1,2-二溴乙烷和醛亚胺在 THF 中在声化学 Barbier 型条件下反应,获得了高产率的区域选择性 α-加合物。在路易斯酸促进的巴比耶型反应条件下也实现了高度区域选择性和立体选择性烯丙基化反应。
