Convenient Indole Synthesis from 2-Iodoanilines and Terminal Alkynes by the Sequential Sonogashira Reaction and the Cyclization Reaction Promoted by Tetrabutylammonium Fluoride (TBAF)
The sequential Sonogashira reaction and the cyclization reaction of various 2-iodoanilines and terminal alkynes in the presence of a palladium catalyst and tetrabutylammonium fluoride (TBAF) gave the corresponding 2-substituted indoles in good yields.
Herein, we describe a photoinitiated and regioselective synthesis of 2-substituted indoles under mild reaction conditions. This biologically privileged scaffold was accessed in good yields from N-aroylbenzotriazoles, a quencher class previously identified using our mechanism-based luminescence screening, and terminal alkynes in the presence of a photocatalyst and blue light irradiation. This straightforward
