title: Ruthenium-catalyzed pyrrole synthesis via oxidative annulation of enamides and alkynes.
abstract: An efficient and regioselective ruthenium-catalyzed oxidative annulation of enamides with alkynes via the cleavage of C(sp(2))-H/N-H bonds is reported. The reactions can afford N-acetyl substituted or N-unsubstituted pyrroles by altering the reaction conditions slightly.
