A unique method has been developed using an interlocking building-block model equipped with magnets to illustrate the catalytic asymmetric hydrogenation of beta-keto esters by a BINAP-ruthenium complex to enhance students' understanding of this process. A BINAP-ruthenium block model, mimicking the coordination environment around the metal center in the real complex, can be used to convert the beta-keto ester model into a beta-hydroxy ester model. This model was used to provide a greater understanding of the essence of the catalytic reaction and to assist students in their understanding of its mechanism.
