assignments were based on spectroscopic analysis and comparison with data for previously isolated plakortolides and revealed both phenyl- and methyl-terminating side chains attached to the plakortolide core. Plakortoperoxides A–D (5–8) each contained a second 1,2-dioxine ring; a cis configuration for the side chain endoperoxide ring was determined by a low-temperature NMRstudy and by comparison of chemical
