SYNTHESIS OF LARIAT DIAZACROWN ETHERS WITH TERMINAL AMINO GROUPS IN THE SIDE CHAINS
Keywords:
diazacrown ethers, N,N'-substituted, terminal amino groups, lariat effectAbstract
Treatment of diazacrown ethers with N-(haloalkyl)- and N-(haloethoxy)phthalimides gives the corresponding N,N'- substituted diazacrown ether. Hydrazinolysis of the latter then gives diazacrown ethers with terminal primary amino groups in the side chain. Their reductive methylation using formaldehyde in formic acid gives the dimethylamino derivatives. The presence of a lariat effect was demonstrated by treating the compounds obtained with picrates of alkali and alkaline-earth metals.
