[Object]
The present invention provides a process for preparing optically active cyclic sulfoxides.
[Means for solution]
A process for preparing an optically active cyclic sulfoxide, which is characterized by reacting a cyclic thioether with cumene hydroperoxide or isopropylcumyl hydroperoxide in the presence of alcohol, water or a mixture of water and alcohol and in the presence of a complex of an optically active tartaric acid diester and a titanium (IV) alkoxide in an inert solvent.
目的
本发明提供了一种制备光学活性环状氧化硫的工艺。
[解决方法]
一种制备光学活性环状氧化硫的工艺,其特征在于:在醇、水或水和醇的混合物存在下,以及在光学活性酒石酸二酯和钛(IV)烷氧化物的络合物存在下,在惰性溶剂中,使环状硫醚与过氧化氢己烯或过氧化氢异丙苯反应。
