L-Proline triflate has been used as an efficient catalyst for an improved and rapid one-pot synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles in good yields. The benefit of this approach is its operational simplicity and the catalyst can be easily recovered and reused without any loss of activity.
L-脯氨酸三氟甲磺酸酯已被用作一种有效的催化剂,用于以良好的收率改进和快速一锅法合成 2,4,5-三取代和 1,2,4,5-四取代咪唑。这种方法的好处是操作简单,催化剂可以很容易地回收和重复使用,而不会损失任何活性。
