Synthesis and Characterisation of a Series of New Aza-Crown Ethers

A series of aza-crown ethers were synthesised by the in situ reduction of Schiff base crown ethers that were obtained by the condensation of a dialdehyde with a diamine in methanol solution. The aza-crown ethers were characterised by elemental analysis, FAB-MS, IR, and 1H NMR. They were obtained in...

Description
Summary:A series of aza-crown ethers were synthesised by the in situ reduction of Schiff base crown ethers that were obtained by the condensation of a dialdehyde with a diamine in methanol solution. The aza-crown ethers were characterised by elemental analysis, FAB-MS, IR, and 1H NMR. They were obtained in good yields.
