Abstract
The structures of three new diterpenoids, acutilol A, acutilol A aceta te and acutilol B have been determined by a combination of spectral me thods. The new compounds are based upon the common pachydictyane carbo n skeleton but possess unusual Delta(1,10) double bonds. The acutilols are potent feeding deterrents against both temperate and tropical her bivorous fishes and sea urchins, suggesting that these molecules provi de an effective chemical defence.
