The acid-catalyzed rearrangement of organic peroxides is generally associated with C–C-bond cleavages (Hock and Criegee rearrangements), with the concomitant formation of an oxocarbenium intermediate. This article describes the tandem process between a Hock or Criegee oxidative cleavage and a nucleophilic addition onto the oxocarbenium species (in particular a Hosomi–Sakurai-type allylation), under
有机过氧化物的酸催化重排通常与 C-C 键断裂(Hock 和 Criegee 重排)相关,并伴随形成氧碳鎓中间体。本文描述了在 InCl 3 催化下,Hock 或 Criegee 氧化裂解与氧碳鎓物种上的亲核加成(特别是 Hosomi-Sakurai 型烯丙基化)之间的串联过程。应用于2-取代苯并氧环类化合物(色满和苯并氧杂环己烷)的合成,包括沙利佐坦2-(氨甲基)色满部分的合成,以及红球菌酰胺B的全合成。
