Spirocycles: An expedient enantioselective synthesis of highly substituted spirotetracyclic indolenines and oxindoles has been realized by an organocatalyzedcascadereaction between α,β‐unsaturated aldehydes and active methylene compounds. In the case of aliphatic α,β‐unsaturated aldehydes, subsequent steps were required to transform the crude cascade mixture into characterizable products with E‐ethylidenyl
