A method for the synthesis of amide‐containing molecules was developed using vinyl azides as an enamine‐type nucleophile towards carbon electrophiles, such as imines, aldehydes, and carbocations that were generated from alcohols in the presence of BF3⋅OEt2. After nucleophilic attack of the vinyl azide, a substituent of the resulting iminodiazonium ion intermediate migrates to form a nitrilium ion,
一种含酰胺的分子的合成方法是使用叠氮化物的乙烯基作为向碳亲电子,例如在BF的存在下由醇生成的亚胺,醛和碳正离子的烯胺型的亲核试剂开发3 ⋅OEt 2。在对叠氮化乙烯进行亲核攻击后,所得亚氨基重氮离子中间体的取代基迁移形成硝酸根离子,将其水解得到相应的酰胺。
