中文摘要：

以天然樟脑为原料，经5步反应合成了手性樟脑烷二醇（endo-1），实验发现endo-1在放置过程中可完全转化为exo-1，其结构经1^H NMR，13^C NMR和ESI-MS表征。以exo-1为配体，研究了不同氧化剂及其用量对钛催化的不对称硫醚氧化反应的影响。结果表明，用枯烯过氧化氢作氧化剂时，亚砜主产物构型出现逆转，而用叔丁基过氧化氢则不会。

英文摘要：

Chiral camphanediol（endo-1） was synthesized from natural camphor by a five-step reaction. The complete conversion of endo-1 to exo-1 was found during storage. The structure was characterized by 1^H NMR, 13^C NMR and ESI-MS. Using exo-1 as ligand, the effects of various oxidants and their amounts on titanium-catalyzed enantioselective sulfoxidation were investigated. The results showed that the configuration of the product sulfoxide was reversed using eumene hydroperoxide as the oxidant, but it was not using t-butyl hydroperoxide as the oxidant.
