A variety of N ‐(furan‐3‐ylmethylene)benzenesulfonamides were obtained by a gold(I)‐catalyzed cascade reaction from easily accessible starting materials. The reaction pathway involves a rarely observed 1,2‐alkynyl migration onto a gold carbenoid. This observation further enriches gold carbenoid chemistry with regard to group migration.
