中文摘要: |
研究了一种结构新颖、合成路线简单的手性二胺催化的Diels-Alder反应,考察了各种Brønsted酸助催化剂、温度、溶剂和手性二胺分子中上不同的取代基对反应的影响。研究结果表明:该类催化剂在催化Diels-Alder反应中表现出较高的催化活性和中等的立体选择性。 |
英文摘要: |
A series of chiral diamines with novel rigid structure have been successfully applied in the Diels-Alder reaction. The effect of reaction conditions such as Brønsted acid, temperature, solvent and different substitutes on the diamines was also extensively investigated. The results showed that the Diels-Alder reaction processed smoothly with high yield and moderate enantiomeric excess under the optimized reaction conditions. |
