摘要
A novel [1＋1] Schiff-base macrocyclic compound 3 has been synthesized from precursor 1, 1,3-bis（2＇- formylphenoxy）-2-propanol, and precursor 2, resorcinol-bis（4-aminophenyl）ether, via condensation and cyclizaction using Ba2＋ as template. The macrocycle 3 was further reduced giving saturated macrocycle 4. The structures of 3 and 4 were characterized by elemental analysis, ~H NMR, IR, and MS spectra, and their structures were determined via single crystal X-ray diffraction studies. X-ray diffraction analysis revealed that the macrocyclic compound 3 has a folded conformation, and the corresponding reduced product 4 adopts a twisted and folded conformation due to its flexible nature. ~ 2013 Bi-Xue Zhu.
