Snyderol derivatives from Laurencia obtusa collected in Corsica

Publication date: February 2019Source: Biochemical Systematics and Ecology, Volume 82Author(s): Hélène Esselin, Sylvain Sutour, Ange Bighelli, Félix TomiAbstract8-keto-10-dehydrobromo-γ-snyderol (1), a new sesquiterpene exhibiting the unusual γ-snyderane skeleton, was isolated from the ethyl acetate extract of Laurencia obtusa collected in Ajaccio (Corsica, France). (1) was isolated and fully characterized by detailed spectroscopic analysis. Six known compounds were identified after column chromatography steps using a 13C NMR based computerized method developed in our laboratory: α-snyderol (2), two rearranged derivatives of α-snyderol (3,4), 8-keto-10-dehydrobromo-β-snyderol (5), β-snyderol (6) and 8-hydroxy-β-snyderol (7).Graphical abstract
