## 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 stereoselectiv
