AbstractA highly efficient copper/GanPhos-catalyzed 1,3-dipolar cycloaddition of azomethine ylides is reported. This viable transformation provides a series of optically active spiro[dihydronaphthalene-2,3′-pyrrolidine]s, bearing one spiro quaternary and three tertiary stereogenic centers, in good yields and with high ee values. This protocol features high diastereo- and enantioselectivity, broad substrate scope and mild reaction conditions.
