  A simple and direct method for the preparation of dialkyl 1-(benzyloxycarbonylamino) alkylphosphonates and dialkyl or diphenyl α-(benzyloxycarbonylamino)benzylphosphonates in high yields consists of the three-component reaction of benzyl carbamate, an alkanal or a benzaldehyde, and a dialkyl (or dipbenyl)-phosphite in acetyl chloride at 0°C (for alkanals) or in acetic acid containing thionyl chloride at 20-70°C (for benzaldehydes). Removal of the benzyloxycarbonyl group by standard methods or selective hydrolysis of the dialkyl phosphonate moiety leads to the formation of derivatives of aminoalkylphosphonic acids bearing free amino or acidic functions, which are useful intermediates in phosphonopeptide synthesis.

  Acetyl chloride is used successfully in the synthesis of 1-aminoalkyl- and amino(aryl)methylphosphonic acid derivatives by a three-component condensation reaction involving diethyl phosphoramidate, aldehydes and diphenyl phosphite. Furthermore, in the reaction of benzyl carbamate, aldehydes and phosphorus(III) chloride, acetyl chloride facilates the formation of alkyl hydrogen 1-(benzyloxycarbonylamino)alkylphosphonates or aryl(benzyloxycarbonylamino) methylphosphonates, key intermediates in the synthesis of phosphonopeptide with a P-N bond. In comparison with other methods, the present variation affords wider scope of application including the use of some aliphatic aldehydes, fair yields and mild reaction conditions.

  An excellent method for a one-pot conversion of N-protected α-aminoalkylphosphonous acids into the corresponding monomethyl phosphonates, using thionyl chloride in methanol, has been devised. N-Protected monomethyl α-aminoalkylphosphonates are valuable intermediates in the preparation of phosphapeptides.
