The synthesis and structural characterisation of coumarin derivatives of some macrocyclic ethers was reported. They were obtained from 1,2,3-trihydroxy and 1,2,4-trihydroxyphenols by reacting with ketoesters. The reaction of dihydroxy coumarins with dichlorides of polyglycols in potassium carbonate/DMF/water afforded the crown ethers in good yields.
