Dialdehyde + Diamine-Polymer or Macrocycle?

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 en...

Zusammenfassung:	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.
