seco-plakortolides (10−13), and three plakortones (14−16), were isolated from the Australian sponge Plakinastrella clathrata. Structuralelucidation, including relative configurational assignment, was based on extensive spectroscopic analysis, while the absolute configurations of 1−4 were deduced from 1H NMR analyses on MPA esters derived from Zn/AcOH reduction products. Diastereomeric sets of plakortolides
