Abstract
Two novel diterpenoid 2'-monoglyceryl esters, austrodorin-A (7) and austrod orin-B (8), which contain the isocopalane skeleton with an uncommon oxygena ted substitution pattern, have been isolated from the skin of the Antarctic nudibranch Austrodoris kerguelenensis. Structures and relative stereochemi stries have been established by NMR methods, whereas the absolute configura tion was suggested by comparison of their CD profiles with those of model c ompounds.
