Abstract :

Gold(I) complexes containing monodentate PIII ligands built upon methylated α-cyclodextrins have been synthesized and assessed in the cycloisomerization of 1,6-enynes, two of the reactions studied involving prochiral substrates. Their performance was compared with that of previously reported mononuclear and dinuclear α- and β‐cyclodextrin-based Aucomplexes. Enantiodiscrimination was found to be strongly dependent on the ability of the ligand to position metal-coordinated substrates inside the cyclodextrin core.
