An efficient method for the synthesis of various primary and secondary amines through a zirconium(IV) isopropoxide–mediated reductive amination reaction of aldehydes and ketones is reported. A series of different aldehydes, ketones and amines were used leading to the expected amino products in moderate to excellent yields. The mechanistic rationale of this reaction has been postulated through the formation
据报道,通过异丙醇锆(IV)介导的醛和酮的还原胺化反应,可以有效地合成各种伯胺和仲胺。使用了一系列不同的醛,酮和胺,以中等到极好的收率得到了预期的氨基产物。已通过形成瞬时亚胺物种和使用(R)-苯基乙胺作为手性诱导剂的非对映选择性形式推测了该反应的机理原理,从而以中等至优异的收率获得了预期的产物,非对映选择性高达100%。
