A novel and convenient method for synthesizing unsymmetrical N-benzyloxycarbonyl-protected 1-amino-1-arylalkylphosphonate mixed diesters
Abstract
Unsymmetrical N-benzyloxycarbonyl-protected 1-amino-1-arylalkylphosphonate mixed diesters were synthesized using a one-pot reaction involving benzyl carbamate, aromatic aldehydes and alkoxydichlorophosphine, followed by treatment with alcohols in the presence of triethylamine. The reactions were followed by 31P NMR and a mechanism is proposed.
