The gold-catalyzed cyclization of various α-amino-ynone derivatives gave the corresponding pyrrolin-4-ones in high yields. Moreover, the use of gold(III) oxide as catalyst allows a moderate to total stereocontrol during the cyclization. These pyrrolin-4-ones are highly useful intermediates for the synthesis of functionalized pyrrolidines and other natural products.
