The common Caribbean octocoral Erythropodium caribaeorum has yielded several additional chlorinated diterpenes since the first survey (1).

In another study, erytrolide A (66), isolated from the Caribbean octocoral Erythropodium caribaeorum, is considered to originate in nature from terpenoid 65 by a DPM rearrangement, probably the first observation of the involvement of this photoreaction in the production of natural products [47]. In order to test this possibility, compound 65 was irradiated in benzene for 3 h, using a medium-pressure Hg arc lamp, affording 66 in 87%... 

Erythrolide A (86) has been thought to be produced naturally from the diterpenoid 87 by a light-induced di-Jt-methane rearrangement (Scheme 6.33), because both compounds were isolated from the Caribbean octocoral Erythropodium caribaeorum.656 In order to confirm this hypothesis, the potential precursor 87 was irradiated under various conditions and 86 was obtained in relatively high chemical yields.

Aquariolides A-C are a new class of tricyclic diterpenes isolated from the gorgonian Erythropodium caribaeorum, first cultivated in an aquarium then harvested in the wild in the Dominican Republic. This original C5/C5/C9 skeleton is formed from briarane and erythrane carbon skeletons by di-Jt-methane and vinylcyclopropane rearrangements. No biological property seems to have been reported (Taglialatela-Scafati et al., 2002, 2003). Sinulobatin D is a rare tetracyclic diterpene discovered in Sinularia nanolobata, harvested in Japan.
