The stereoselective oxidative rearrangement of disubstituted unactivated olefins has been achieved using a hypervalent iodine(III) reagent. The aryl group undergoes 1,2-migration to give tert-α-arylated aldehydes (as acetals). The preparation of these aldehydes/acetals, especially containing a tert-benzylic stereocenter, has remained challenging. This migration-based method provides a complementary
使用高价碘(III)试剂可实现双取代未活化烯烃的立体选择性氧化重排。芳基经历1,2-迁移,生成叔-α-芳基化醛(缩醛)。这些醛/缩醛,特别是含有叔苄基立体中心的醛的制备仍然具有挑战性。这种基于迁移的方法为访问此类分子的已知基于α取代的方法提供了一种补充方法。
