β-hydroxycyclohexanones with up to three chiral centres have been synthesized in a stereocontrolled way using the novel anionic oxy-Cope (AOC) rearrangement of acyclicenol ethers. The first examples of compounds containing an aldehyde and an enol ether in a 1,5 relationship are reported. Stereocontrol in the cyclisation of these compounds by a 6-(enolendo)-exo-trig intramolecular aldol reaction has been

a stereoselective route to β-hydroxycyclohexanones using the aldol reaction, the Takai alkylidenation, a novel anionic oxy-Coperearrangement of acyclic enol ethers and an intramolecular aldol reaction. The stereoselectivity of the acid-induced, 6-(enolendo)-exo-trig, intramolecular, aldol reaction between an aldehyde and an enol ether has been investigated. The strong preference for an axial hydroxyl
