The 18-crown-6 derivative possessing two hydroxyl groups was prepared from the Diels–Alder adduct of 1,7-(1,2-ethanediylidene)-18-crown-6 with dimethyl 2-butynedioate. By using the crown ether as the key intermediate, novel bis-crown and double-armed crown ethers having the 18-crown-6 residue were synthesized, and their abilities to extract metal picrates were investigated.
