Asymmetric synthesis of silicon compounds was achieved in high optical yield by the substitution reaction of some chiral 5,6-dimethoxy-1,3,2-dioxasilacycloheptane derivatives with organometallic reagents followed by lithium aluminium hydride reduction. These starting dioxasilacycloheptanes were obtained by the coupling reaction of (S,S)-2,3-dimethoxybutanediol and corresponding prochiral dialkyldichlorosilanes
通过一些手性 5,6-二甲氧基-1,3,2-二氧硅杂环庚烷衍生物与有机金属试剂的取代反应,然后氢化铝锂还原,以高光学产率实现了硅化合物的不对称合成。这些起始二氧硅杂环庚烷是通过 (S,S)-2,3-二甲氧基丁二醇和相应的前手性二烷基二氯硅烷的偶联反应获得的。
