Abstract
Five new amino acid derivs. were isolated from the New Caledonian sponge Jaspis carteri, together with known bengamides A and B. The structures of the new compds. were detd. by interpretation of their spectral data and by comparison with spectral data of known bengamides. Bengamides G (I), and H, I, and J are simply the tridecanoate and pentadecanoate analogs of the original bengamides A and B, whereas bengamide K (II) is a caprolactam formamide deriv. of bengamide B.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
