Bifunctional Chiral ImPy‐Carbene Ligands. H‐Bonding Controlled Reactivity and Enantioselectivity in Au(I)‐Catalysis

Chemistry – A European Journal, Volume 31, Issue 35, June 23, 2025.
A new class of catalytically highly efficient bifunctional imidazopyridine (ImPy)‐based gold(I) complexes was synthesized. The ligands are based on tetrahedral C‐stereogenic centers derived from straightforward chiral pool synthesis. Unprecedented cycloisomerization products of 1,6‐enynols were observed in excellent enantioselectivity up to 99:1 er ...
