Graphene oxide is utilized as an environmentally friendly and efficient catalyst for an ultrasound mediated multi-component coupling reaction that involves aldehyde, amine/ethylacetoacetate and diethyl phosphite/urea, under solvent-free conditions, leading to the bioactive α-aminophosphonates and 3,4-dihydropyrimidin-2-ones with excellent yield.

Esters of 1-phenyl-1-pyridylaminomethanephosphonates generally cannot, or only in poor yields be prepared by the usual methods by treatment of the appropriate Schiff base with diethyl or diphenyl phosphite.However, it was found that these phosphonates are
