By introducing slight structural modifications to a D4‐symmetric coordination capsule, we succeeded in isolating the nearly enantiopure capsules (P)‐ and (M)‐2 a(BF4)4. Chiral guest, dibenzyl 4,4′‐diacetoxy‐6,6′‐dimethyl‐[1,1′‐biphenyl]‐2,2′‐dicarboxylate (3) was encapsulated within the dissymmetric cavity of 2 a(BF4)4, resulting in a high diastereoselectivity of >99 % de. The encapsulated guest was
