(1R,1'R,2S,4R)-1,7,7-Trimethylspiro[bicyclo[2.2.1]heptane-2,2'-[1,3]dithiolane] 1'-oxide, (1R,2S,3'R,4R)-1,7,7-trimethylspiro[bicyclo[2.2.1]heptane-2,2'-[1,3]dithiolane] 1',1',3'-trioxide, and (1R,4R)-1,7,7-trimethylspiro[bicyclo[2.2.1]heptane-2,2'-[1,3]dithiolane] 1',1',3',3'-tetraoxide were synthesized by oxidation of camphor ethylene dithioacetal with m-chloroperoxybenzoic acid at different substrate-tooxidant ratios. The structure of the products was proved by IR and NMR spectroscopy and X-ray analysis.
(1R,1'R,2S,4R)-1,7,7-三甲基螺-[双环[2.2.1]庚烷-2,2'-[1,3]二硫环] 1'-氧化物、(1R,2S,3'R,4R)-1,7,7-三甲基螺-[双环[2.2.1]庚烷-2,2'-[1,3]二硫环] 1',1',3'-三氧化物以及(1R,4R)-1,7,7-三甲基螺-[双环[2.2.1]庚烷-2,2'-[1,3]二硫环] 1',1',3',3'-四氧化物是通过香茅基乙二硫代缩醛与m-氯过苯甲酸在不同底物与氧化剂比例下进行氧化反应合成的。产物的结构通过红外光谱、核磁共振光谱和X射线衍射分析得到了证实。
