Synthesis of N-(bisphosphonomethyl)-aza-15-crown-5 and N-(bisphosphonomethyl)-aza-18-crown-6 ethers as artificial ion channels: An approach to channel-type molecular structures

摘要

We report the synthesis and characterization of 2 new N-(bisphosphonomethyl)-aza-15-crown-5 1a and N-(bisphosphonomethyl)-aza-18-Crown-6 ethers 1b designed to further investigate the supramolecular assemblies based on exocyclic functional groups of crown ethers.
