One-pot three-component syntheses of -aminophosphonates from a primary amine, quinoline-4-carbaldehyde and a phosphite in the presence of MCM-41@PEI as an efficient nanocatalyst

摘要

Synthesis of some quinoline-containing -aminophosphonate derivatives via Kabachnik-Fields reaction between an amine, quinoline-4-carbaldehyde and a phosphite in the presence of polyethylene imine grafted mesoporous nanomaterial (MCM-41@PEI) as a nanocatalyst was investigated. The reactions were carried out in one pot and under solvent free conditions at 50-80 degrees C to afford the corresponding -aminophosphonates in high yields and short times.
