well-known organocatalysts for the HSiCl3 reduction of imines; however, custom design of catalysts is based on trial-and-error experiments. In this work, we have used a combination of computational calculations and experimental work, including kinetic analyses, to properly understand this process and to design optimized catalysts for the benchmark (E)-N-(1-phenylethylidene)aniline. The best results have
脯氨酰胺是众所周知的用于 HSiCl 3还原亚胺的有机催化剂;然而,催化剂的定制设计是基于反复试验的。在这项工作中,我们结合了计算计算和实验工作(包括动力学分析)来正确理解该过程并为基准(E) -N- (1-苯基亚乙基)苯胺设计优化的催化剂。使用由 4-甲氧基苯胺和N-新戊酰保护的脯氨酸衍生的酰胺获得了最好的结果,其催化过程比未催化过程快了近 600 倍。机理研究表明,超分子复合催化剂-HSiCl 3 -基质组分的形成,涉及氢键断裂和脯氨酰胺中昂贵的构象变化,是整个过程中的重要步骤。
