Synthesis of aminomethyl derivatives of phosphonocarboxylates of the furan series

Resumo

By reaction of halomethyl derivatives of phosphonocarboxylates of the furan series with sodium azide corresponding azidomethyl compounds were synthesized. Treating them with triphenylphosphine in ethanol results in primary amines. Seven of the twelve possible position isomers of the aminomethyl phosphonocarboxylates were obtained. Method was found of selective dealkylating phosphonates leaving intact the ester group present in the molecule.
