complex for 1‐alkylaminopentenes diminishes resolution efficiency. Nevertheless, the relative cyclization rate for the two diastereomeric substrate–catalyst complexes remains in a typical range of 7–10:1. Plausible attractive π interactions between the aryl substituent and either the metal center or the aromatic system of the bis(triarylsilyl)‐substituted binaphtholate ligand may explain increased stability
