摘要：
An efficient methodology for the synthesis of alpha-aminophosphonates has been developed taking advantage of the tertbutyldimethylsilyl triflate activated addition of diethyl phosphite to N-benzyl nitrones; derived from chiral alpha-alkoxy and alpha-(Boc-amino) aldehydes. The stereoselective carbon-phosphorus bond-forming reaction proceeded smoothly to give a-(hydroxyamino)phosphonate intermediates as the primary adducts, which were subsequently converted into the corresponding polyhydroxylated alpha-amino- and alpha,beta-diaminophosphonates by conventional reductive processes.
