An unprecedented system of gold and oxidativeNHC relay catalysis was developed, which enables highly enantioselective cascade annulation between readily available α-amino-ynones with enals to afford pyrrole-fused lactones in high yield and excellent level of enantioselectivity. The lactone products could be readily converted to diverse densely functionalized pyrroles and pyrrolin-4-ones in high yields
