Abstract
Five new chlorinated peptides (5)-(9) have been isolated from a Dysidea sp. and identified by two-dimensional NMR spectroscopy. The absolute stereoche mistry of the metabolites was deduced by chemical correlation with S-(-)-4, 4,4-trichloro-3-methylbutanoic acid (10) and with an alcohol (11). (C) 2001 Elsevier Science Ltd.
