M. Kobayashi et al., MARINE TERPENES AND TERPENOIDS .19. STRUCTURE OF A TETRACYCLIC NORCEMBRANOLIDE DERIVATIVE ISOLATED FROM THE SOFT CORAL SINULARIA-DISSECTA, Journal of chemical research. Synopses, (5), 1995, pp. 188-189
Dissectolide A (1), isolated from the soft coral Sinularia dissecta to
gether with two known compounds, is shown to be a highly strained norc
embranolide derivative having cyclopentane, cyclohexene, cycloheptane
and alpha,beta-unsaturated gamma-lactone ring systems.
