TOVAROL AND OTHER GERMACRANE DERIVATIVES FROM THAPSIA VILLOSA

Teresa, Joaquin de Pascual,Moran, Joaquin R.,Hernandez, Jose M.,Grande, Manuel

, p. 1779 - 1784 (2007/10/02)

Four tovarol, two epoxytovarol ( = shiromodiol) and one diepoxytovarol esters were the new germacrane esters isolated from the roots of Thapsia villosa var. minor.The structures of these substances were assigned on the basis of spectral data and chemical correlations with shiromodiol.The acid catalysed rearrangement of tavarol yielded 1(10),4-bulgaradiene-8-ol. Key Word Index - Thapsia villosa; Thapsia villosa var. minor; Umbelliferae; germacrane derivatives; tovarol, shiromodiol and epoxytovarol esters; 1(10),4-bulgaradiene-8-ol.
