摘要

The preparation of polyfunctional diarylamines of type 1 is an important goal in synthesis since these building blocks are present in many pharmaceuticals and various fine chemicals. There are two approaches to such target molecules [1] involving either the generation of a nucleophilic amino synthon 2 which will react with an electrophilic aromatic reagent (Ar+XÀ 3, path a in Scheme 1). This retrosynthetic analysis has been successfully ...
