Sempervirol

A new synthesis of sempervirol has utilized the condensation " of j8-cyclocitral with 4-isopropyl-3-methoxybenzyl chloride to afford (108). Cyclization of the corresponding ketone gave the tricyclic system (109) which was converted into sempervirol. A novel rearrangement of the angularly fused cyclobutanone (110) to (111) forms the basis of a synthesis of potential intermediates for conversion into the diterpenoid alkaloids. [Pg.126]

Salvia limbata yielded two known abietane diterpenoids ferruginol and abieta-8,11,13-triene. Salvia multicaulis Vahl syn. S. acetobulosa has yielded six new abietane and norabietane diterpenoids in addition to 1-oxoferruginol, 3-oxo-ferruginol, horminone, pisiferal, 18-oxoferruginol and sempervirol. [Pg.673]
