Dipolar cycloaddition: A highly efficient copper(I)‐catalyzed enantioselective [3+2] cycloaddition reaction of 1,3‐fused cyclic azomethine ylides and nitroalkenes has been developed. This method provides access to functionalized tropane scaffolds with several quaternary and tertiary stereocenters in a single step under mild reaction conditions.
