Abstract
Three novel tetraphenolic bis-spiroketals, prunolides A-C (1, 3, and 4) hav e been isolated from the Australian ascidian Synoicum prunum. The structure s were determined from NMR spectroscopic data and from an X-ray analysis of prunolide A. The prunolides contain a unique 1,6,8-trioxadispiro[4.1.4.2]t rideca-3,10,12-triene-2,9-dione carbon skeleton. The known compound rubroli de A (5) was also isolated.
