Treatment of acyclic α-hydroxyalkyl α,β-unsaturated sulfoxides with t-BuOOH/VO(acac)2 results in rapid oxidation to the unsaturated sulfones followed by an unusual regio- and stereoselective epoxidation at the unsaturated sulfones; this methodology has been applied to the preparation of carbohydrate-like fragments.
用t -BuOOH / VO(acac)2处理无环α-羟烷基α,β-不饱和亚砜会导致快速氧化为不饱和砜,然后在不饱和砜处发生不寻常的区域和立体选择性环氧化;该方法已经应用于制备
