Enantioselective gold( i )-catalyzed cyclization/intermolecular nucleophilic additions of 1,5-enyne derivatives
Résumé
An enantioselective Au(I)-catalyzed cyclization/nucleophilic addition process is developed, starting from 1,5-enyne substrates. A broad scope of ON N-and C-nucleophiles was introduced in order to provide the corresponding chiral cyclopentene derivatives in moderate to high yields and up to 96:4 enantiomeric ratio.
