offers a convenient route for the synthesis of six-membered cyclicacetals, which are common substructures of polyketide natural products. When conjugated 6-hydroxyhexynoates are used as starting materials, either five-membered cyclic E-enol ethers or the corresponding acetals can be obtained by simply choosing the appropriate reaction solvent. NMR spectroscopic studies were carried out to determine the
