A one-pot transformation of hydroxylated propargylic benzoate into chiral ketones featuring an O-heterocycle is realized via sequential gold catalysis and basic hydrolysis. The gold chemistry entails tandem 3,3-sigmatropic rearrangement and asymmetric cyclization of hydroxylated allenyl ester intermediates, which is achieved via asymmetric metal-ligand cooperation. The products were formed with good
