通过烯丙基溴化锌对手性亚胺的两次不对称加成,合成了光活性的双烯丙基化的新型手性二胺。
A novel chiral diallylic diamine has been synthesized through double addition of allyl zinc bromide to chiral imines in this contribution.
而烯丙基溴预处理可以使反应立体选择性从通常的生成S-型产物过量转变为R-型产物过量,优化处理条件后能使R-CHBE的e。
On the contrary, pretreating with allyl bromide could turn the stereoselectivity of this asymmetric reduction reaction from mainly producingS-CHBE to R-CHBE.
