Cationic gold(I)-catalyzed intramolecular cyclization of γ-hydroxyalkynones into 3(2H)-furanones
"Chemical Equation Presented" The combination of (p-CF 3C6H4)3PAuCl and AgOTf generates a powerful catalyst for the intramolecular cyclizations of readily available y-hydroxyalkynones un-der mild conditions. The
