[reaction: see text] Lanthanide triflates along with proline-derived ligands have been found to be efficient catalysts for enantioselective conjugate addition of nucleophilic radicals to enoates. N-Acyl oxazolidinones, when used as achiral additives, gave meaningful enhancements in the ees for the product.
[反应:见正文]已发现镧系三氟甲磺酸酯与脯氨酸衍生的配体一起是将亲核基团对映选择性共轭加成烯酸酯的有效催化剂。N-酰基恶唑烷酮用作非手性添加剂时,可显着提高产品的ee。
