Abstract
The structure of ostreocin D, a palytoxin analog isolated from the marine d inoflagellate Ostreopsis siamensis, was found to be 42-hydroxy-3,26-didemet hyl-19,44-dideoxypalytoxin by detailed 2D NMR analyses of intact ostreocin D and its ozonolysis products. Partial stereochemical assignments were done . This result indicates that the dinoflagellate O. siamensis is one of the biogenetic origins of palytoxin.
