Total syntheses of two marine sesquiterpenes, aplysin 1 and debromoaplysin 2, are described. The key step involves a diastereoselective, sulfur mediated radical cyclisation of diene 5 to 7 which simultaneously creates the sterically demanding aplysin skeleton and establishes the relative configuration of the three contiguous stereogenic centres.
