Enantioselective Total Synthesis of 3β‐Hydroxy‐7β‐kemp‐8(9)‐en‐6‐one,a Diterpene Isolated from Higher Termites

The first total synthesis of the title diterpene was accomplished starting from the Wieland–Miescher ketone. A diastereoselective sulfa‐Michael addition enabled the generation of the delicate β,γ‐unsaturated ketone moiety, while the tetracyclic kempane skeleton was readily constructed through domino metathesis.
