【発明の名称】光学活性形ステロイド側鎖合成用中間体の製造方法

Document Type and Number:

Japanese Patent JP2562999

Kind Code:

B2

Abstract:

This invention provides a novel method for the preparation of optically active arylalkylsulfone derivatives, having a chiral center in the alkyl moiety in either the (R)- or the (S)-configuration. These optically active sulfones find use in the stereospecific synthesis of steroid or vitamin D compounds having chiral center at either carbon 24 or carbon 25 of the side chain.
