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

3-dihydrofurans is reported. These non-aromatic heterocycles containing a useful coupling handle are accessed via Cu-catalyzed intramolecular cyclization of 1,2-dibromohomoallylic alcohols, which are themselves available in just two steps from aromatic and aliphatic aldehydes and ketones. Molecular dynamics simulations using the simple substrates and key geometric parameters provide a rationale for the selectivities
