The mysterious cyclizations of gold: An asymmetric gold(I)‐catalyzed formal [3+3] cycloaddition of 2‐(1‐alkynyl)‐2‐alken‐1‐ones with nitrones has been developed. Compound 1 was found to be an effective and reliable chiral catalyst, as well as the commonly used 2, for this gold‐catalyzed reaction. Tf=trifluoromethanesulfonyl.
