The Mediterranean alcyonacean Alcyonium ( = Parerythropodium) coralloides (Pallas, 1766) is shown here to contain coralloidolide F ( = (+)‐(3a‐ R *, 7 R *, 8 R *, 9 R *, 12 R *, 12a S *)‐8,9‐epoxy‐1,3a,6,7,8,9,10,11,12,12a‐decahydro‐3a‐hydroxy‐12‐isopropenyl‐2,5‐dimethyl‐1‐oxocyclopfintacycloundecene‐9,7‐carbolactone; (+)‐ 2 ), the first example of a 2,6‐cyclized cembranolide. Structural assignments are mainly based on ID and 2D NMR and MS data.
