Synthesis of Some Benzo-14-crown-4 Ethers Substituted to 7,8-Dihydroxy-3-phenylcoumarin Derivatives

7,8-Dihydroxy-3-phenylcoumarin derivatives reacted with l,2-bis-(3-tosyloxypropoxy)benzene in CH 3 CN/alkali carbonate to furnish 3-phenylchromenone-14-crown-4 ether derivatives, which were identified with elemental analysis, IR, 1 H NMR, 13 C NMR and MS spectroscopy.
