Sideritis canariensis

Sideritis canariensis contains trachylobane, (—)-kaurene, and some 7)S,18-dihydroxy-( — )-kaur-16-ene, together with trachinodiol [(7fi, 18-dihydroxytrachyl-obane (93)] and trachinol (7)5-hydroxytrachylobane). The structure of trachinodiol was established by interconversion with trachylobane. Oxidation gave a keto-ester, which on bromination and dehydrobromination afforded an a -unsaturated ketone whose substitution pattern located the carbonyl group at C-7. [Pg.145]
