catalytic nucleophilic addition reaction of 3‐hydroxybenzofuran‐2‐carboxylic acid derivatives to 2H‐azirines for the high‐yield synthesis of NH‐aziridines with a 3‐coumaranone substituent has been developed. The Ph3PAuNTf2‐catalyzed reaction is diastereoselective to give predominantly (RS,SR)‐isomer of aziridine in good yield. The Ni(hfacac)2‐catalyzed reaction affords aziridines in up to 98% yield and low
