complex: The asymmetric one‐step construction of multiplestereocenters in complex spirocyclicoxindoles was achieved with very high fidelity by using distinct organocascade reactions utilizing two organocatalysts, each activating different carbonyl compounds (see scheme; TMS=trimethylsilyl). The complementary approaches demonstrate the potential of organocascadecatalysis to face challenging synthetic
