Gold mesoionic carbenes having a chiral sulfoxide group attached to the C4 position of five membered ring have been prepared and tested as catalysts in cycloisomerization enynes. These new are very efficient, with moiety playing key role their activity N1-substituent control regioselectivity these processes.
