Products of the Caribbean: The palau'amine derivative tetrabromostyloguanidine 1 was isolated from the sponge Stylissa caribica and the elucidation of its structure with the focus on the relative configuration is discussed in detail. Results from NMR studies and molecular calculations suggest that the relative configuration for members of the palau'amine family differs from that earlier reported.
