Optically active esters were conveniently obtained from the corresponding racemic alcohols or esters by lipase-catalyzed transformation, followed by sulfation. Sulfation by sulfurtrioxide pyridine complex enabled facile isolation of optically active esters by extraction instead of laborious column chromatography. The method would be especially advantageous on a large scale.
通过脂肪酶催化转化,然后硫酸化,从相应的外消旋醇或酯方便地获得旋光酯。三氧化硫吡啶复合物的硫酸化能够通过萃取而不是费力的柱色谱法轻松分离旋光酯。该方法在大规模上将是特别有利的。
