| 摘要 | Four new compounds, rearranged noreremophilan-8,6-olide, rearranged dinoreremophilanone, epoxy gamma-lactone, and 2 alpha-hydroxyermophil-11-en-9-one, along with eremophilenolides related to ligularol and other known terpenoids, were isolated from Ligularia virgaurea (ligularol type) collected from the northern Sichuan Province of China. Three of the new compounds had degraded and unique structures. The absolute configuration of 2 alpha-hydroxyermophil-11-en-9-one was determined on the basis of density functional theory calculation. The back octant rule cannot be applied to this compound because of the contribution of the hydroxy group to the front octant. (C) 2013 Elsevier Ltd. All rights reserved. |
