Three tricyclic sesquiterpenes, sesquithuriferol (1), α- (3) and β-duprezianene (4) were isolated from the essential oil of the wood of Juniperus thurifera L. The structure and absolute configuration of 1 was established on the basis of 2D INADEQUATE and other 2D NMR spectra, as well as by chemical correlations. The structure of 3 and 4 were elucidated by 2D NMR spectra and confirmed by their synthesis
从杜鹃属木材的香精油中分离出了3种三环倍半萜,倍半萜酚(1),α-(3)和β-杜戊烯(4)。在2D INADEQUATE的基础上建立了1的结构和绝对构型。和其他2D NMR光谱,以及化学相关性。通过2D NMR光谱阐明3和4的结构,并通过1的甲苯磺酰基溶剂重排进行合成证实了3和4的结构。
