Two rings in one sweep: A domino metathesis of the bicyclic dienyne 4 (TBS=tert‐butyldimethylsilyl) obtained from a catalytic enantioselective Diels–Alder reaction as the key process enabled the efficient preparation of the tetracyclic diterpenes kempene‐2 (1), kempene‐1 (2), and 3‐epi‐kempene‐1 (3).
