Preparation of New α-Aminophosphonate Derivatives by Kabachnik-Fields Reaction Using a Recyclable Catalyst

Abstract EN

A convenient and efficient synthetic method for the preparation of some new α-aminophosphonate derivatives via a one-pot three-component system has been achieved using Amberlite IRC-748 as a recyclable catalyst.

This method not only provides an excellent complement for the synthesis of α-aminophosphonates but also avoids the use of hazardous acids or expensive/toxic Lewis acids and harsh reaction conditions.

Most of the synthesized compounds (4a–o) exhibited activity against bacteria/fungi strains and moderate DPPH radical scavenging activity.
