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.
