An efficient chiral ligand, (1R,5R)-1-(1'-dimethylaminoethyl)-2-isopropylidene-5-methylcyclohexanol, has been developed for the enantioselective addition of diethylzinc to some prochiral aldehydes to afford S-alcohols. The overall conversion rate was 80-98% with excellent enantiomeric excess (79-98%).
已经开发了一种有效的手性配体 (1R,5R)-1-(1'-二甲基氨基乙基)-2-isopropidene-5-methylcyclohexanol,用于二乙基锌与一些前手性醛的对映选择性加成,以提供 S-醇。总转化率为 80-98%,对映体过量 (79-98%)。
