for the one-pot synthesis of diethyl α-aminophosphonates from aldehydes, amines and diethylphosphite (Kabacknik-Fields reaction) in SDS micellar solution in aqueous media is described. The synthesis of α-aminophosphonates in the present study represents a three-component reaction in which no intermediate formation of either an imine or α-hydroxyphosphonate was observed. aldehydes - amines - α-aminophosphonates

The reaction of trialkylphosphites, dialkyl phenylphosphonites or alkyl diphenylphosphinites with N-alkylalkanimines in the presence of hydrogen chloride gives dialkyl 1-(alkylamino)alkylphosphonates, alkyl [1-(alkylamino)alkyl]phenylphosphinates or [1-(alkylamino)alkyl]diphenylphosphine oxides respectively, via Arbusov-like reaction of iminium salts generated ‘in situ’ from N-alkylalkanimines. This

Recent drug discovery efforts have focused primarily on allosteric inhibition of hFPPS and the discovery of non-bisphosphonate drugs for potentially treating nonskeletal diseases. Hit-to-lead optimization of a new series of thienopyrimidine-based monosphosphonates (ThP-MPs) led to the identification of analogs with nanomolar potency in inhibiting hFPPS. Their interactions with the allosteric pocket of

Hydrolysis of 3-pyridylmethyl(amino)phosphonates by means of 20% aq. hydrochloric acid gave corresponding 3-pyridylmethyl(amino)phosphonic acids, as expected. However, hydrolysis of 2- and 4-pyridylmethyl(amino)phosphonates led to decomposition of the phosphonates with a cleavage of CP bond and formation of the corresponding amines. The leaving phosphorus moiety was identified as phosphoric acid.
