N-Cbz-Diaryl hydrazides undergo acid-catalyzed [3,3] sigmatropic rearrangement to afford N-Cbz-1,1'-biaryl-2,2'-diamines. The resultant products can be versatile synthetic platforms for a wide variety of C-2- and/or nonsymmetric axially chiral ligands and organocatalysts.
N-Cbz-二芳基酰肼在酸催化下发生 [3,3] σ 重排,得到 N-Cbz-1,1'-联芳基-2,2'-二胺。所得产品可以是用于各种 C-2-和/或非对称轴向手性配体和有机催化剂的通用合成平台。
