Ligand‐Dependent Chemoselectivity in Gold‐Catalyzed Reactions between Anthranils and Diynamides. Formation of Spiro Azacyclic Compounds versus 1‐Imino‐1H‐Indene‐3‐Carboximidamides

open access: yesChemistryEurope, EarlyView.
Gold catalysts direct anthranil/diynamide reactions: PPh3AuCl/AgNTf2 forms spiro azacycles (indole intermediate confirmed), while P(t‐Bu)2(o‐biphenyl)AuCl/AgNTf2 yields indene carboximidamides via a proposed mechanism. Gold‐catalyzed reactions between anthranils and diynamides have been investigated, and their reaction chemoselectivity relies on the ...
