Production of Macrocyclic Polyether Benzo-15-Crown-5 and its Functional Derivatives

“…Despite growing interest in these compounds over recent years, the current number of papers on the synthesis of macrocyclic polyethers is extremely small [10][11][12][13][14][15] . For example, benzo-15-crown-5 can be produced using Williamson synthesis reaction, featured by interaction between catechol (orto-dihydroxybenzene) and tetraethylene glycol dichloride (1,10-dichloro-3,6,9-trioxadecane) over sodium hydroxide in the n-butanol media (30-h inertatmosphere boiling).…”
