Nitrogen-containing aromatic compounds are ubiquitous in nature.They often exhibit a wide range of biological activities.Therefore,chemists have been studying on the preparation of them for a long time as well as developing various methods for their derivatization.Recently,the direct oxidation of nonaromatic cyclicsubstrates to prepare selectively substituted aromatics has been one of research focuses.In which,the functionalized aromatics could be obtained via C―C,C―N,C―S and C―Se bonds formation without the directing groups in one step.This paper reviews the recent progress in the construction of functional quinoline and indole by this method,and proposes future development prospects in this field.
