A convenient procedure is proposed for the synthesis of cryptands by the alkylation of bis-N-(2-tosylaminoethyl)diaza-crown ethers with dibromides in the two-phase system: aqueous sodium hydroxide/toluene.

MACROHETEROCYCLES. PART 44. FACILE SYNTHESIS OF AZACROWN ETHERS AND CRYPTANDS IN A TWO-PHASE SYSTEM

A facile procedure is proposed for the preparation of azacrown ethers and cryptands by condensation of dibromides or ethylene glycol bis(toluene-p-sulphonate)s with acyclic bis(sulphonamide)s or with bisdiazacrown ethers, respectively.The reaction was carried out in a two-phase system of aqueous alkali-toluene (benzene)in the presence of quaternary ammonium salts as phase transfer catalysts.The catalytic activity decreased in the sequence: Bu4NI ca.Bu4NBr > Bu4NCl > Bu4NHSO4 > Et3NCH2C6H5NCl.Maximum yields of twelve-membered azacrown ethers are obtained when lithium hydroxide is used, while crown ethers of larger size are observed in the presence of sodium or potassium hydroxides; this may be due to a template effect.
