with the olefin. The amide group is derived from a nitrile and a water molecule which serve as nucleophiles for the overall three-component reaction. The bromoamidation is general for a broad range of olefins and nitriles. This reaction pathway provides access not only to vicinal bromoamides but also to N-acyl aziridines and oxazolines. From these, many types of amines and amino alcohols can be prepared
描述了一种将
溴原子和酰胺氮反式加成到烯烃双键上的方法。该方法由许多实例说明,涉及使用 N-
溴酰胺和
路易斯酸作为与烯烃反应的 Br+ 源。酰胺基团衍生自腈和
水分子,它们在整个三组分反应中充当亲核试剂。
溴酰胺化通常适用于范围广泛的烯烃和腈。该反应途径不仅提供了获得邻位
溴酰胺的途径,还提供了获得 N-酰基
氮丙啶和
恶唑啉的途径。由这些,可以制备多种类型的胺和
氨基醇。提供了描述非对映选择性和区域选择性偏好的例子。还描述了类似的
