The eleven‐membered sulfur‐containing heterocycle 1 is formed from ethylene oxide and SO2 in the presence of cesium salts in 20% yield. The structure of 1 was determined by X‐ray diffraction analysis. Compounds such as 1 are interesting because the complexing properties of crown ethers can be finely tuned by the introduction of other heteroatoms.
