An efficient ruthenium(II) catalyst enabled broadly applicable oxidative alkyne annulations with electron-rich enamines to provide diversely decorated pyrroles, even in an aerobic fashion with air as the ideal oxidant.

An efficient and regioselective ruthenium-catalyzedoxidative annulation of enamides with alkynes via the cleavage of C(sp2)–H/N–H bonds is reported. The reactions can afford N-acetyl substituted or N-unsubstituted pyrroles by altering the reaction conditions slightly.
