    • The present invention relates to a production method of an optically active form of a compound represented by formula (II) 1 wherein ring A is a benzene ring optionally having substituent(s); R1 is H, a hydrocarbon group optionally having substituent(s), an acyl group or an acyloxy group; R2, R3 and R4 are each H, an alkyl group optionally having substituent(s), an alkoxy group optionally having substituent(s) or an amino group optionally having substituent(s); X is N or CH; Y is N or CH; and * shows an asymmetric center, or a salt thereof, which includes reacting a compound represented by the formula (I) 2 wherein each symbol is as defined above, or a salt thereof, with an excess amount of an oxidizing agent in the presence of a catalyst for asymmetric induction, and provides an efficient production method of an optically active sulfoxide derivative in high yield on an industrial large scale by a convenient method, while achieving an extremely high enantiomer excess.
    • 本发明涉及式(II)表示的化合物的光学活性形式的制备方法,其中环A是任选具有取代基的苯环; R 1是H,任选具有取代基的烃基,酰基或酰氧基; R 2,R 3和R 4各自为H,任选具有取代基的烷基,任选具有取代基的烷氧基或任选具有取代基的氨基; X为N或CH; Y为N或CH; 和*表示不对称中心或其盐,其包括使式(I)表示的化合物或其盐,其中每个符号如上定义,或其盐与过量的氧化剂在 用于不对称诱导的催化剂,并且通过方便的方法在工业上大规模提供高产率的光学活性亚砜衍生物的有效制备方法,同时实现极高的对映体过量。
