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