The 24‐membered macrocycle 1 is surprisingly generated from ( S )‐2,2′‐dihydroxy‐1,1′‐binaphthyl‐3,3′‐dialdehyde [( S )‐( 2 )] and ( R,R )‐1,2‐diamino‐1,2‐diphenylethane, whereas in the same reaction ( R )‐ 2 yields the polymeric Schiff base as expected. Macrocycle 1 can be used for an economical and simple enantiomeric resolution of 2 .
