alcohols react with oxoammonium salts, undergoing a tandem elimination/allylic oxidation to provide an allylicether product in a single step. This mode of reactivity provides a rapid entry into allylicethers from certain benzylic tertiary alcohols. The allylicether may be cleaved under reductive conditions to reveal the allylic alcohol.
herein reported. The combination of PhI(OAc)2 and Cs2CO3 proves highly efficient at inducing the direct 1,2-C to N migration of primary amines, which can be applied to the preparation of both acyclic and cyclic amines. A mechanistic study shows that the rearrangement proceeds via a concerted mechanism.
本文报道了由高价碘(III)试剂介导的伯胺的氧化重排。证明PhI(OAc)2和Cs 2 CO 3的组合在诱导伯胺从1,2-C向N的直接迁移方面非常有效,可用于制备无环胺和环胺。机理研究表明,重排通过协同机制进行。
