oxidation of the allyl alcohols 9a or 9b afforded the pure ketones 3a or 3b MnO2 oxidation of the alcohols 10a or 10b furnished the aldehydes 4a or 4b. – Surprisingly, the italicene epoxides 2a or 2b rearranged with diluted HCl to the italicene ethers (epoxyacorenes) 5a or 5b, which previously were isolated from Lantana and Helichrysum oil. – The odor of 3a, 3b, 4a, 4b and 5a was evaluated.
三环倍半萜烃italicene(氧化1A)或它的10差向异构体1B(从先前分离的蜡菊油)与SEO 2得到italicene -5-酮(的混合物3A),italicen-15-人,(4A),italicen -5- -ol(9a)和italicen-15-ol(10a)或它们的10-受体3b,4b,9b,10b,而商用α-copaene(6)仅反应生成α-copaen-15-al(7)和α-copaen-15-ol(8)。烯丙醇9a或9b的琼斯氧化得到纯酮3a醇10a或10b的MnO 2或3b氧化使醛4a或4b氧化。-令人惊奇地,环氧化物italicene 2A或2B用稀HCl重新排列到italicene醚(epoxyacorenes)图5a或5b中,这在以前是从分离马缨丹和蜡菊油。–评估了3a,3b,4a,4b和5a的气味。
