Okinawan coral Clavularia viridis is also biosynthesized by the unrelated Caribbean coral, Pseudoplexaura porosa, indicating that the biosynthesis of 5 may be widespread in coral. The biogenesis of preclavulone-A from arachidonic acid occurs by lipoxygenation at C(8), migration of oxygen from C(8) to C(9) and ring closure, in a process (marine pathway) which contrasts sharply with the mammalian (endoperoxide)
The enantioselective total synthesis of preclavulone-A methylester and its diastereomer was achieved from enantiomerically pure 5 in a stereocontrolled manner. The absolute stereochemistry of naturally occurring preclavulone-A methylesters was determined by comparison of the [α]D value.
