An aromatic sesquiterpene, cuparene (IV), has been isolated from Chamaecyparis thyoides, Biota orientalis and Widdringtonia. Cuparene gives terephthalic acid on oxidation with dilute nitric acid and (+)-camphonanic acid (III) on prolonged treatment with ozone and is therefore 1-(4-methylphenyl)-1:2:2-trimethylcyclopentane. Oxidation of cuparene with chromium trioxide gives the corresponding substituted
一种芳香倍半萜烯,铜(IV),已从Chamaecyparis thyoides,Biota Orientalis和Widdringtonia中分离出来。Cuparene给出了氧化对苯二甲酸用稀硝酸和(+) -对长期治疗camphonanic酸(III)用臭氧,因此1-(4-甲基苯基)-1:2:2三甲基环戊烷。用三氧化铬氧化铜烯,得到相应的取代的苯甲酸铜酸(V)。已经发现该酸与先前从维德灵顿氏菌属物种中分离出的倍半萜烯酸(“酸Ⅲ”)相同,现在也从硫代Chamaecyparis thyoides中分离出该倍半萜烯酸(“酸III”)。
