ABSTRACT New proline diamide organocatalysts with Pro-Phe peptide bonds were synthesized and their catalytic activities in asymmetric direct aldol reactions of aliphatic ketones with aromatic aldehydes were investigated. Catalyst 6a showed good enantioselectivity at 0 °C in the presence of p-nitrobenzoic acid as cocatalyst in water. GRAPHICAL ABSTRACT
摘要合成了具有 Pro-Phe 肽键的新型脯氨酸二酰胺有机催化剂,并研究了它们在脂肪酮与芳香醛的不对称直接醛醇反应中的催化活性。在对硝基苯甲酸作为助催化剂在水中存在时,催化剂 6a 在 0 °C 下表现出良好的对映选择性。图形概要
