- Аннотация: A convenient synthetic method was developed for new diazacrown compounds that contained at polyether cavity polyfunctional cyclohexene or cyclohexane fragments of definite configuration. The synthetic procedure consists in fusion in toluene of equimolar quantities of anhydrides of 4-cyclohexene and 4,5-trans-dibromocyclohexane-cis-1,2-dicarboxylic acids with hydroxy-substituted diazacrown ether. The crown compounds synthesized under complexing conditions with AgBF4 undergo disproportionation yielding bis-crown compounds.
