摘要
在室温条件下,以过氧化氢水溶液为氧源,非手性磷酸作为催化剂催化硫醚与缩硫醛的氧化反应,以良好到优秀的收率合成一系列亚砜化合物.该方法反应条件温和,时间短,收率高,且非对映选择性高.
Hydrogen phosphates have been explored as organocatalysts for the oxidation of a series of aryl alkyl sulfides and 1,3-dithianes derived from aldehydes with aqueous hydrogen peroxide(H2O2) as the terminal oxidant. The corresponding sulfoxides are obtained in moderate to excellent yield(up to 99%) with excellent diastereoselectivity(up to99∶1 dr).
