title: Access to coumarins by rhodium-catalyzed oxidative annulation of aryl thiocarbamates with internal alkynes.
abstract: A Rh-catalyzed annulation of aryl thiocarbamates with internal alkynes via C-H bond activation has been developed. This protocol provides a new route to 3,4-disubstituted coumarins.
