Özet
Starting from ethyl propionylacetate, and ethyl 2-ethylacetoacetate we prepared 4-propyl-7,8-, 4-propyl-6,7-, 3-ethyl-4-methyl-7,8- and 3-ethyl-4-methyl-6,7-dihydroxy-2H-chromenones which were allowed to react with the bis-dihalides or ditosylates of glycols in DMF/Na2CO3 to afford the 6,7- and 7,8-chromenone derivatives of 12-crown-4, 15-crown-4 and 18-crown-6. The products were identified using ir, 13C and 1H nmr, ms and high resolution mass spectroscopy. The cation selectivities of chromenone crown ethers with Li+, Na+ and K+ cations were estimated from the steady state emission fluorescence spectra of free and cation complexed chromenone macrocyclic ethers in acetonitrile.
