The stereoselective gold(I)-catalyzed cascade cyclization of 1,5-enynes and alkoxycyclization of 1,6-enynes with chiral auxiliaries has been developed, affording, after hydrolysis, synthetically challenging enantioenriched ketones. This chiral auxiliary approach is an alternative to the use of complex chiral catalysts in gold(I)-catalyzed asymmetric cyclizations.
