Flex control: Malonate and tert‐butoxycarbonyl (Boc)‐protected imines react in the presence of the flexible catalyst 1 to furnish the S or the R adduct depending upon the solvent used. Kinetic analyses in this enantiodivergent organocatalysis show that enthalpy–entropy compensation explains this behavior.
挠性控制:
丙二酸酯和叔丁氧羰基(Boc)保护的
亚胺在挠性催化剂1的存在下反应,根据所使用的溶剂提供S或R加合物。在这种对映发散性有机催化中的动力学分析表明,焓-熵补偿解释了这种行为。
