Ketones in the catalytic three-component one-pot Kabachnik-Fields synthesis of α-amino phosphonates

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