Monoperphtalic acid oxidizes (−)-linaloöl in the cold to the expected diastereomeric pair of 6,7-dihydro-6,7-epoxy-linaloöls. These substances are unstable. On heating or on treatment with acid they are converted to a mixture of two pairs of diastereomeric oxides C10H18O2. The pair A/B, amounting to about 90% of the secondary product, are known as the linaloöl-oxides. They are shown to be tetrahydrofuran
在冷却下,单过苯二甲酸将(-)-linaloöl氧化为预期的非对映异构体对6,6-7,6-dihydro-6,7-epoxy-linalools。这些物质是不稳定的。在加热或用酸处理时,它们被转化为两对非对映体氧化物C 10 H 18 O 2的混合物。A / B对占次级产物的90%,被称为芳樟醇氧化物。它们显示为具有结构IV A和IV B的四氢呋喃衍生物。C / D对是结构III C和III D的非对映体四氢呋喃衍生物。
