| Sumario: | The two new diterpenes, vierol, (1) [(-)kaurane-16a,18-diol] and powerol (3) [(-)kaurane-7B,16a-diol] have been isolated from Sideritis canariensis Ait. 1 was obtained by partial synthesis from epicandicandiol (7), and 3 was related with (-)kauranol (6) and (-)kauren-7B-oil acetate (11). Reduction of the acetoxy-aldehyde 14 by the method of Huang-Minlon and posterior acetylation gave 11, (-)isokauren-7B-ol-acetate (17) and (-)kauran-7B-ol acetqate (18). |
