Highly efficient access to iminoisocoumarins and alpha-iminopyrones via AgOTf-catalyzed intramolecular enyne-amide cyclization.
Iminoisocoumarins and alpha-iminopyrones are prepared via Sonogashira coupling and AgOTf-catalyzed 6-endo-dig O-cyclization of the enyne-amide system in dichloroethane, in one pot or stepwise, respectively.
