A novel gold(I)-catalyzed cascade cycloisomerization of a variety of propargylic esters leading to unsymmetrically substituted naphthalenes has been developed. This domino process involves an unprecedented tandem sequence of 1,3- and 1,2-migrations of two substantially different migrating groups. It is believed that this transformation proceeds via formation of 1,3-diene intermediate or its equivalent
