Cobalt-catalyzed enantioselective C–H/N–H annulation of aryl sulfonamides with allenes or alkynes: facile access to C–N axially chiral sultams

Herein we report a cobalt-catalyzed enantioselective C–H/N–H annulation of aryl sulfonamides with allenes and alkynes, using either chemical or electrochemical oxidation. By using O(2) as the oxidant, the annulation with allenes proceeds efficiently with a low catalyst/ligand loading of 5 mol% and t...
