Enantioselective gold(i)-catalyzed cyclization/intermolecular nucleophilic additions of 1,5-enyne derivatives

Abstract

An enantioselective Au(I)-catalyzed cyclization/nucleophilic addition process is developed, starting from 1,5-enyne substrates. A broad scope of O-, 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.
