A New Bromo Diterpene, <i>epi</i>-Aplysin-20, and <i>ent</i>-Isoconcinndiol from the Marine Mollusc <i>Aplysia kurodai</i>

Abstract

Abstract A New brominated labdane-type diterpene, epi-aplysin-20, and ent-isoconcinndiol have been isolated from the marine mollusc Aplysia kurodai: the structure of epi-aplysin-20 has been established on the basis of the spectroscopic data and chemical transformation.
