title: New analogue of gymnodimine from a Gymnodinium species.
abstract: A spiroimine, gymnodimine B (1), was isolated from cells recovered by filtration from cultures of a marine dinoflagellate, Gymnodinium sp. Its structure was identified by one- and two-dimensional NMR spectroscopy and mass spectrometry. Gymnodimine B is similar in structure to gymnodimine (2) but contains an exocyclic methylene at C-17 and an allylic hydroxyl group at C-18.
