search for green chemistry methods for the enantioselective reduction of ketoesters Saccharomyces cerevisiae- and ruthenium-catalyzed reactions in water have been investigated. The highest enantiomeric excesses for the reduction of α- and β-ketoesters have been obtained by S. cerevisiae. Chiral ruthenium catalysts are active for the reduction of all ketoesters with low to moderate enantioselectivities
在寻找绿色化学方法以对映体还原酮酸酯的过程中,已经研究了酿酒酵母和钌催化的水中反应。酿酒酵母获得了用于还原α-和β-酮酸酯的最高对映体过量。手性钌催化剂对于还原所有酮酯具有低到中等对映选择性的活性,这取决于底物和配体的性质。有趣的是,对于几种底物,已经根据催化方法或配体的结构获得了羟基酯的两种对映体。
