Synthesis of the azapodands with phosphoryl terminal groups

Abstract

© 2016 Taylor & Francis Group, LLC.New lipophilic phosphorylated azapodands with different substituents at the nitrogen atom were synthesized via the Kabachnik–Fields reaction in the three-component system: di-p-tolylphosphinous acid– formaldehyde–1,8-diamino-3,6-dioxaoctane. The reaction was carried out in toluene or acetonitrile media, with p-toluenesulfonic acid acting as a catalyst.
