A novel and highly convenient catalytic variant of the synthesis of α-aminophosphonates on basis of the Kabachnik-Fields reaction [three-component reaction of ketones, diethylphosphite and either benzylamine (series a) ofammonium carbonate (series b)] in the presence of tetra-tert-butylphthalocyanines has been developed. This method affords α-aminophosphonates in acceptable yields for various ketones

an extremely efficient catalyst for the synthesis of α-aminophosphonates. A three-component reaction (3-CR) of an amine, an aldehyde or a ketone, and a di-/trialkyl phosphite (Kabachnik−Fields reaction) took place in one pot under solvent-free conditions to afford the corresponding α-aminophosphonates in high yields and short times. The use of solvent retards the rate of the reaction and requires a

Reactions of carbocyclic, heterocyclic, and steroidal ketones with benzylamine and diethyl phosphite in a catalytic three-component “one-pot” synthesis of α-amino phosphonates were studied. The activities of mono-and binuclear complexes of tetra(tert-butyl)phthalocyanines as catalysts for this process were compared.
