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

The configuration and conformation of some diastereomeric 4‐hydroxy‐cis‐ and ‐trans‐1‐oxadecalins were inferred by 1H and 13CNMR spectroscopy. The results obtained indicate that the cis‐fused compounds are conformationally homogeneous, having the oxygen atom attached to the cyclohexyl ring in the axial position. In the 13CNMR spectra, the magnitude of the α and γ substituent effects of the hydroxy
