New [1+1] and 62-membered [2+2] Schiff base macrocycles containing a 2,6-diamidopyridine subunit have been synthesized by condensation reaction of the precursors pyridine-2,6-dicarboxamide and 1,10bis(2'-formylphenyloxy)decane in the presence of phosphoric acid via a one-pot process.The cyclocondensed products were effectively isolated by gel column chromatography and characterized by 1H NMR,FTIR,mass spectrometry and X-ray analysis.The two macrocycles have a twisted structure,and not an open ‘circular'conformation in the solid state.
