More rings for your rhodium: Rhodium‐catalyzed intermolecularalkynehydroacylations deliver γ‐hydroxy‐α,β‐enones, which can be cyclized in situ to deliver di‐ and trisubstituted furans. Functionalization of the intermediates using Heck chemistry allows the formation of regioisomeric furans. The use of an alternative RhI catalyst delivers 1,4‐dicarbonyl compounds and hence pyrroles, thiophenes, and
