A novel organophosphorus compound containing the structure of both β-amino acid and B-aminophosphonate is designed and synthesized. Arbuzov reaction with P(OEt)3, the N-Boc protected iodide 3 cannot provide the desired product but 2-oxazolidinone 4 because of the neighboring-group participation of the Boc moiety.To avoid the intramolecular participation of the carbamates, the Ts protecting group is employed and the Ts-protected iodide 5 affords the target product successfully.
