Three new chlorinated marine steroids, yonarasterols G, H and I, isolated from the Okinawan soft coral, Clavularia viridis
摘要:
Three new chlorinated marine steroids, yonarasterols G, H and I, were isolated from the Okinawan soft coral Clavularia viridis. Their structures including the absolute configuration were determined based on the results of spectroscopic analysis and chemical conversion. (C) 2001 Elsevier Science Inc. All rights reserved.
Four newcytotoxic steroids named stoloniferone-a (7a), -b (7b), -c (7c), and -d (7d) were isolatedfrom the stoloniferan Okinawan softcoralClavularia viridis and their absolute stereostructures were elucidated.
