- 中文摘要: Five new ochtodane class monoterpenes have been isolated from two collections of the red alga Portieria hornemanni and their structures elucidated by spectroscopic analysis. These compounds contained 4,4-dimethylcyclohexa-2,5-dienone in common and differed in the C2 side chain structure. Some of them showed mild cytotoxicity. Also discussed is the mechanism of the transformation of 2-chloro-1-hydroxyochtoda-3(8),5-dien-4-one, a related labile compound reported previously, into 4,5-dimethylbenzo[b]furan.
