Six sesquiterpenoids 1–6, formally derived from (+)-(S)-nerolidol by oxidative cyclization, have been isolated for the first time from commercial cabreuva oil. Whereas the two tetrahydrofurans 5 and 6 have already been described, the four bicyclic ethers (cabreuva oxides A–D) 1–4 are new. The structures of 1–4 are confirmed by synthesis and their absolute configurations are shown to be 3S. The organoleptic
六倍半萜1 - 6,从(+)形式上衍生- (小号通过氧化环化)-nerolidol,已经分离首次从商业卡布雷乌瓦油。而两个四氢呋喃5和6已经被描述的,四个双环醚(卡布雷乌瓦氧化物A-d)1 - 4是新的。1 – 4的结构通过合成得到证实,其绝对构型显示为3S。讨论了合成Cabreuva氧化物的感官特性。
