| Abstract: | Multi-ester type biscrown ether compound(I) was prepared by the reaction of 6-bromoacetacetic ester dibenzo-16-crown-5(7) with phenyl-methyl ether-2,6-diformic acid potassium salt in anhydrous DMF at refluxed temperature, and color biscrown ether compound(II) was prepared by the reaction of 4′-aminobenzo-15-crown-5(12) with 2,2′(O-formoyl naphthyl)ethyl ether (9) in anhydrous ethanol at 40 C under N2. New compounds(I, II) were characterized by IR,1H NMR, MS and elemental analysis. Supported by the National Natural Science Foundation of China Niu Changrong: born in December, 12, 1938, Professor |
