One-Pot N-Arylation of indoles directly from N-arylsulfonylindoles via consecutive deprotection and SnAr reactions with activated aryl halides

Article abstract of DOI:10.1248/cpb.57.321

An efficient one-pot step by step t-BuOK-mediated procedure for the synthesis of N-arylindoles has been developed in moderate to good yields. The protocol involves the consecutive deprotection of N-arylsulfonylindoles as latent indoles and subsequent SnAr
