Goldcycle redesigned: By utilizing the alkynophilic effect of gold(I) complexes, a new method for the synthesis of highlysubstituted cis‐2,6‐tetrahydropyranones was developed, which represents a catalytic surrogate of the Petasis–Ferrier rearrangement (see scheme). Of particular interest is the unique effect the phosphine ligand has on the diastereoselectivity of the alkyl groups at the 2‐ and 6‐positions
