Palladium(0)-Catalyzed Heck Reaction/CH Activation/Amination Sequence with Diaziridinone: A Facile Approach to Indolines

Indolines are important moieties present in various biologically significant molecules and have attracted considerable attention in synthetic chemistry. This paper describes a Heck reaction/CH activation/amination sequence for forming indolines using di‐tert‐butyldiaziridinone. The reaction process likely proceeds via a pallada(II)cycle, which is converted into an indoline by oxidative addition to the diaziridinone and two subsequent CN bond formations. Good form: Indolines are important moieties present in various biologically significant molecules. Described is the title sequence for forming indolines with di‐tert‐butyldiaziridinone. The reaction process likely proceeds via a pallada(II)cycle, which is converted into an indoline by oxidative addition to the diaziridinone and two subsequent CN bond formations.
