ω-phenyl polyketide peroxides, plakinicacidsK and L, were isolated from a two-sponge association of Plakortis halichondroides and Xestospongia deweerdtae. The absolute configurations of the remote dimethyl-branched stereocenters in plakinicacidK were assigned by degradation of plakinicacidK to a long-chain naphthamide and analysis by liposomalcirculardichroism (L-CD) and comparison with synthetic
