摘要: A process for upgrading to essentially 100% enantiomeric excess the optical purity of an organoborane intermediate represented by the formulae:
wherein Icp is isopinocampheyl and R * is a unsubstituted or substituted, acyclic or cyclic alkyl having from 4 to 30 carbon atoms, comprising the steps of hydroborating cis- alkene, a trans-alkene or a tertiary-alkene with monoisopinocampheylborane or diisopinocampheylborane, obtaining a solid organoborane and recrystallizing the solid organoborane to obtain an enantiomeric excess of essentially 100% ee of said organoborane.摘要翻译: 将由下式表示的有机硼烷中间体的光学纯度升级至基本上100%对映异构体的方法:IcpBHR *或Icp2BR *,其中Icp是异蒎烯基,R *是未取代或取代的,无环或环状的具有4-30碳 包括以下步骤:将顺式烯烃,反式烯烃或叔丁烯与单取代蒎烷基硼烷或二异蒎烷基硼烷加成硼,得到固体有机硼烷并使固体有机硼烷重结晶,得到基本上100%ee的所述有机硼烷的对映体过量。
