A highly efficient, mild and general cyclization reaction of hydroxy exo-(propargyl)Co2(CO)6 cations leading to medium-sized (6 to 9 membered) cyclic ethers is described. The reaction is highly stereoselective when defined stereocenters are encountered in the linear precursor, providing a way to obtain fused cyclic ethers in their enantiomeric forms.
