- Title

- Abstract
Product selectivity control for the synthesis of imidoylindoles and 4-alkylidenedihydroquinazolines from N-imidoyl- o-alkynylanilines via silver triflate-catalyzed cycloisomerization or tetrabutylammonium fluoride-promoted cyclization is described. The product selectivity depends mainly on the catalyst/promoter used, and on the substituents on the alkyne and amidine functions of the substrates.
