A. Spinella et al., NEW ACETOXY-ENT-PALLESCENSIN-A SESQUITERPENOIDS FROM THE SKIN OF THE POROSTOME NUDIBRANCH DORIOPSILLA-AREOLATA, Tetrahedron letters, 35(46), 1994, pp. 8665-8668
The paper reports the first chemical study of an European Doriopsilla
mollusc. Three new furanosesquiterpenoids, ent- pallescensin-A (2) tog
ether with two acetoxy derivatives (5,6), have been characterized. The
metabolites are distributed either in the skin of the mollusc or in i
ts hermaphrodite gland where the most abundant component is a mixture
of drimane esters (1).
