Bebryazulene, a New Guaiane Metabolite from the Indian Ocean Gorgonian Coral, Bebryce grandicalyx

Bebryazulene (1), a new sesquiterpene having the guaiane skeleton, was isolated from the methanol−chloroform 1:2 extract of the Indian Ocean gorgonian coral Bebryce grandicalyx (Kuekenthal) collected in the lagoon of Mayotte. Structure assignment was based on interpretation of spectroscopic data. Th...

Beschreibung
Zusammenfassung:	Bebryazulene (1), a new sesquiterpene having the guaiane skeleton, was isolated from the methanol−chloroform 1:2 extract of the Indian Ocean gorgonian coral Bebryce grandicalyx (Kuekenthal) collected in the lagoon of Mayotte. Structure assignment was based on interpretation of spectroscopic data. This new metabolite was very labile and reacted with 4-phenyl-3H-1,2,4-triazoline-3,5-dione to yield an unexpected adduct.
