Palladium-catalyzed oxidative synthesis of SF5-indoles

Abstract

Due to its specific physic-chemical properties, the pentafluorosulfanyl group is beginning to find many important applications in material industries and life science. However, synthetic methods leading to SF5-substituted aromatics and heterocycles have remained largely underdeveloped. Herein, we present an efficient one-pot Pd-catalyzed C–H oxidative cyclization reaction from readily available pentafluorosulfanylaniline. The reaction provides a facile construction of SF5-functionalized indoles with moderate yields.
