Template Synthesis of New Type of Macrocyclic Molecule Derived from Pyridine-2, 6-decarboxaldehyde and 1,2-bis(2-Aminoethoxy) Ethane

Abstract

The cyclic (2+2) template condensation of pyridine-2,6-dicarboxaldehyde with 1,2-bis(2- aminoethoxy) ethane using Pb(SCN)₂ as the metal source gave dinuclear lead (II) complex, Pb₂L₁(SCN)₄ (1), where L₁ is tetra-Schiff-base macrocycle. Treatment of 1 with NaBH₄ in methanol gave a metal-free reduced macrocycle L₂ which has been characterized by ¹HNMR and ESI-MS spectroscopy.
