T1 - Note of clarification about: Oxygenated Terpenoids from the Australian Sponges Coscinoderma matthewsi and Dysidea sp., and the Nudibranch Chromodoris albopunctata [vol. 65, pp. 531–538] JF - Australian Journal of Chemistry JO - Aust. J. Chem. Y1 - 2013 VL - 66 IS - 11 SP - 1461 EP - 1461 KW - UR - https://doi.org/10.1071/CH12010_NC N2 - The isolation and structure elucidation of seven new oxygenated terpenoids and eight known terpene metabolites from marine invertebrates collected at the Inner Gneerings Reef, South East Queensland, is discussed. Investigation of the sponge Coscinoderma matthewsi yielded an epoxylactone derivative (1) of the known furanoterpene tetradehydrofurospongin-1 (2). A chemical investigation of the dissected nudibranch Chromodoris albopunctata provided the new oxygenated diterpenes 12?-acetoxyspongian-16-one (10), 20-acetoxyspongian-16-one (12), 20-oxyspongian-16-one propionate (13) and 12?,20-dioxyspongian-16-one dipropionate (14) in conjunction with three other known diterpene metabolites, while two new chromodorolides, D (17) and E (18), in addition to four known diterpenes were isolated from a Dysidea sp.
