The reaction of 1,2-diols with dimethyl sulfoxide-catalytic molybdenum peroxide in refluxing toluene generally resulted in monoprotection of diols to give 2-methylthiomethoxy-l-ols (Course A) Exceptionally, a) cis-1,2-cyclooctanediol and benzopinacol, and b) 1,2-cyclododecanediol caused C–C bond cleavage (Course B) and monooxidation (Course C), respectively as Scheme 1.
1,2-二醇与二甲亚砜催化的过氧化钼在回流甲苯中的反应通常导致二醇的单保护得到 2-甲硫基甲氧基-1-醇(路线 A)例外,a) 顺-1,2-环辛二醇和苯频哪醇, 和 b) 1,2-环十二烷二醇分别引起 C-C 键断裂(路线 B)和单氧化(路线 C),分别如方案 1 所示。
