method is presented for the asymmetric oxidation of sulfides with H2O2, utilizing a pre-formed manganese complex. Just in the presence of a low catalytic amount of carboxylic acid (CA), a variety of sulfide substrates, including aryl alkyl, aryl benzyl and cyclic sulfides, reacted to form chiral sulfoxides in high yields (up to 95%) and excellent enantioselectivities (>99% ee) under mild conditions. Moreover
提出了一种利用预先形成的锰配合物,用H 2 O 2对硫化物进行不对称氧化的简便,环保的方法。仅在低催化量的羧酸(CA)存在下,各种硫化物底物(包括芳基烷基,芳基苄基和环状硫化物)就以高收率(高达95%)和出色的对映选择性反应形成手性亚砜( ee> 99%)。此外,该方法的实用性已经通过埃索美拉唑和阿苯达唑亚砜(ABZO)的合成得到证明。
