A convenientsynthesis of different types of α-aminophosphonates via one-pot solvent-free three component reactions of aldehydes, amines and phosphites catalyzed by bismuth salts has been investigated. Bismuth triflate is found to be the most effective catalyst for this reaction.
efficient, and general method has been developed for the one-pot, three-component synthesis of α-aminophosphonates from condensation reaction of trimethyl phosphite, aryl aldehydes and aryl amines in the presence of CoCl 2 ·6H 2 O under solvent-free conditions. Thus α -aminophosphonates were synthesized relatively quickly in good yields at roomtemperature.
Sodium Dihydrogen Phosphate as an Efficient Catalyst for One-Pot, Three-Component Synthesis of <font>α</font>-Aminophosphonates Under Solvent-Free Conditions at Room Temperature
and general method has been developed for the one-pot, three-component synthesis of α-aminophosphonates from a condensation reaction of trimethyl phosphite, aldehydes, and amines in the presence of sodium dihydrogen phosphate under solvent-free conditions. Thus, α-aminophosphonates were synthesized relatively quickly in good yields at roomtemperature.
Abstract A simple, efficient, and general method has been developed for the one-pot, three-componentsynthesis of α-amino phosphonates from a condensation reaction of trialkyl phosphite, aldehydes, and amines in the presence of a catalytic amount of succinic acid (8.5 mol %) (for the first time) under solvent-free conditions. The advantages of this protocol are excellent yields, short reaction time
