title: 11 beta, 12 beta-Epoxypukalide, a furanocembranolide from the gorgonian Leptogorgia setacea.
abstract: A furanocembranolide, 11 beta, 12 beta-epoxypukalide (1), C21H24O7, was isolated in trace quantities from the gorgonian Leptogorgia setacea. The structure was determined from detailed 1H-nmr and 13C-nmr analyses and comparison of these spectral data with those of the closely related compounds pukalide (2) and lophotoxin (3). The ultimate origin of 1 is discussed briefly.
