One-pot gold-catalyzed aminofluorination of unprotected 2-alkynylanilines
A tandem gold(I)-catalyzed aminocylization/fluorination and a two-step, one-pot gold(III)-catalyzed cyclization/electrophilic fluorination provide a convenient and general method for the synthesis of 3,3-difluoro-2-substituted- 3H-indoles in good yield un
