摘要:通过两种方法制备以硫原子为唯一手性中心的旋光性亚磺酸盐.首先涉及在旋光性氨基醇存在下对称亚硫酸盐与叔丁基氯化镁的反应.这种新的不对称,对映体选择性合成提供了40-70%对映体过量值的叔丁基磺酸盐.第二种方法是基于外消旋亚磺酸盐与叔丁基氯化镁与旋光性生物碱碱络合后发生的新型动力学拆分.在该反应中形成的回收的亚硫酸盐和亚砜都显示出适度的光学纯度.

摘要:The present invention provides an industrial process for effectively and advantageously preparing optically active 1-substituted amino-2,3-epoxypropanes useful as intermediates for preparing agricultural chemicals and medical products from optically active 1-substituted amino-2,3-propanediols used as raw materials. The present invention also provides useful intermediates. Specifically, an optically active 1-substituted amino-2,3-propanediol (1) is reacted with an orthoacid ester (2) or thionyl chloride (3) to produce a cyclic optically active compound (4), and then a compound (5) containing a halogen atom is prepared by reaction with a ring-opening reaction agent having an ability to introduce a halogen atom X. Finally, an optical active 1-substituted amino-2,3-epoxypropane is prepared by ring-closure reaction in the presence of a base.
