A long‐lost cousin of the binaphthyl family has been found to be readily accessible and configurationally stable. These so‐called IAN‐amines are competent ligands for Zr IV ions that display remarkable diastereoselectivity in the formation of C 2 ‐symmetric 2:1 complexes such as 1 . The ligands of the favored diastereomeric complex are homochiral despite the use of a racemic mixture to make the complex.
