Redox‐Neutral Vicarious‐Type Nucleophilic Amination of Heterocyclic N‐Oxides with Organic Azides

Abstract

AbstractSite‐selective amination of N‐heterocycles is an interesting topic in organic synthesis and drug discovery. We herein present a method for the vicarious‐type nucleophilic amination of azine N‐oxides and cyclic iminoamides using iminyl anions, readily generated from organic azides under basic conditions. The plausible reaction mechanism involving nucleophilic aromatic substitution by iminyl anions is elucidated by a series of mechanistic investigations.
