Sarcophytonolides A–D,Four New Cembranolides from the Hainan Soft Coral Sarcophyton sp.

Four new cembranolide diterpenes, sarcophytonolides A–D ( 1 – 4 ), were isolated from a Hainan soft coral Sarcophyton sp. Their structures were elucidated on the basis of detailed spectroscopic analysis and by comparison with related model compounds.
