This section demonstrates that the unusual impact of the cage on reactivity and enantioselectivity originates in the combined LEF of HM1 and the container PB1. This is done by initially evaluating the combined LEF effects on the RC and TS species along the reaction coordinate. Subsequently, we investigate the role of the LEF in determining the special electronic structures of these species. This was complemented by determining the LEF role on the enantioselectivity of the reaction. And finally, by showing that we can get enantioselectivity at will, by simply flipping the direction of the lateral LEF.
