The reaction of N‐allenamides with alkenyl diazo compounds in the presence of goldcatalysts provided methylidenecyclopentene derivatives resulting from a formal intermolecular [3+2] carbocyclization, a rare process in the gold chemistry of allenes. The participation of the CαCβ bond of the allenamide represents a very unusual regioselectivity in gold‐catalyzed cycloaddition reactions of this type
