The oxidative dearomatization of anilines was combined with a domino Michael addition, providing a series of nitrogen-containing bridged bicyclic compounds in moderate to excellent yields. The bridged bicyclic compound could be converted into the corresponding meta carbon-functionalized aniline derivative via a quinine-catalyzed tandem retro-oxa-Michael addition–aromatization reaction.

A method for stereoselective construction of acyclic all-carbon tetrasubstituted alkenes through insertion of nitrile-substituted trimethylenemethane into the aryl C–N bond in anilines via an aromaticity destruction-reconstruction process is reported. The process involves dearomatization, azo-[3 + 2] TMM cycloaddition and aromatization-triggered rearrangement.

A one-pot synthetic strategy for diarylamines using only aromaticamines as starting materials has been developed. This method involved a PhI(OAc)2-induced oxidative dearomatization of N-sulfonyl protected para-substituted anilines, a Bi(OTf)3-catalyzed imino exchange reaction between N-sulfonyl cyclohexadienimines and aromaticamines, and a CF3COOH/Zn mediated reductive aromatization of the resulting

The gold-catalyzed 1,3-O-transpositionreaction of ynesulfonamides provides a practical synthetic protocol for the synthesis of ynamides under mild conditions. This is the first 1,3-O-transposition example of ynesulfonamides in which a heteroatom is attached to the alkynyl terminal. A plausible mechanism is been proposed on the basis of O-18-labeling and control experiments as well as DFT calculation
