general and quite efficient method developed by using di-tert-butylsilyl bis(trifluoromethanesulfonate) as a new promoter for a Boekelheide-type reaction. The use of a new Boekelheide promoter, which is compatible with amino groups, opens new perspectives in view of its application in intramolecular cyclizations.

氨基烷基)
吡啶 N-氧化物合成的,采用一种通用且非常有效的方法,该方法使用二叔丁基甲
硅烷基双(
三氟甲磺酸酯)作为 Boekelheide 型反应的新
促进剂。鉴于其在分子内环化中的应用,使用与
氨基相容的新 Boekelheide 启动子开辟了新的前景。
