The chiral framework based on 11-aminomefloquine has been utilized for the first time to construct bifunctional organocatalysts. These catalysts demonstrate high enantioselectivity in both Michael additions and Friedel–Crafts reactions across a variety of substrates, achieving up to >99% ee. The distinctive feature is the incorporation of a secondary amine group, offering unique tight hydrogen-bonding
基于11-氨基甲氟喹的手性骨架首次被用于构建双功能有机催化剂。这些催化剂在多种底物的迈克尔加成和弗里德尔-克来福特反应中表现出高对映选择性,实现高达 >99% ee。其显着特点是引入了仲胺基团,在质子化状态下提供独特的紧密氢键结合能力,这一点得到了 DFT 计算的支持。这些有机催化剂的多样性表明它们在多种反应类别中具有广泛的适用性。
