involves the consecutive deprotection of N-arylsulfonylindoles as latent indoles and subsequent S(N)Arreactions with activated aryl halides. This tandemreaction affords an efficient and convenient preparation of N-arylindoles that benefit from prior indoles protection by arylsulfonyl group, and can shorten a reaction sequence and improve synthetic efficiency.
