Intermolecular Nucleophilic Addition Reaction of a C-7 Anion from N-[Bis(dimethylamino)phosphoryl]indole to Electrophiles/Arynes: Synthesis of 7-Substituted Indoles

Abstract

A novel approach for C-7 substitution of N-bis(dimethylamino)phosphinoyl indole by nucleophilic addition of C-7 carbanion to electrophiles and arynes is described and the directing group can be easily removed which provides a facile route for synthesis of 7-functionalized indoles.
