Unexpected results are obtained on treatment of alkene–zirconocene complexes with cyclic enol ethers. The ring size of the enol ether makes the reaction proceed through different mechanisms allowing Z alkenols to be prepared from furan derivatives and cyclobutanes from pyran derivatives (see scheme).
