摘要
A series of promising benzoazacrown ethers with the nitrogen atom conjugated with the benzene ring were synthesized using a novel synthetic procedure based on stepwise transformation of the macroheterocycle. The structures and spectral proper-ties of the resulting benzoazacrown ethers and their complexes with Ca2+ were studied by X-ray diffraction and H-1, C-13, and N-15 NMR spectroscopy including the 2D NOESY technique.
