Permethylated NHC-capped aand b-cyclodextrins (ICyD Me ) Regioselective and enantioselective gold-catalysis in pure water

Water‐soluble NHC‐capped permethylated cyclodextrins with encapsulated copper(I), silver(I), or gold(I) complexes were used as catalysts in neat water for hydration, lactonization, hydroarylation, and cycloisomerization reactions. The cavity of these ligands induced high regioselectivity in hydroarylations, and high enantioselectivities in gold‐catalyzed cycloisomerization reactions giving up to 98 % ee in water
