Condensations of 1,5-bis(2-formylphenoxy)-3-oxapentane (1a) or 1,8-bis(2-formylphenoxy)-3,6-dioxanoctane (1b) podands and 1,8-bis(2-acetylphenoxy)-3,6-dioxanoctane (2) gave two novel crown ethers: tetrakis-(benzo)-31-crown-7 ether (5) and tetrakis(benzo)-34-crown-8 ether (6). Their molecular structures were established by IR, NMR and MS methods.
