Unsymmetrical N-benzyloxycarbonyl-protected 1-amino-1-arylalkylphosphonate
mixed diesters were synthesized using a one-pot reaction involving benzyl c
arbamate, aromatic aldehydes and alkoxydichlorophosphine, followed by treat
ment with alcohols in the presence of triethylamine. The reactions were fol
lowed by P-31 NMR and a mechanism is proposed.
