Abstract

A novel method for the synthesis of N-heterocycles from benzylic ethers/alcohols with o-substituted aniline without using any catalyst and additive is developed. This protocol involves C-O bond cleavage of benzylic ethers, N-benzylation, and benzylic C-H amidation in one pot, the tandem oxidation-cyclization transformation may open the door for the easy generation of N-heterocycles.
