Reaction of commercially available trialkyl phosphites with N-phthalylamino acids gave mixtures of seven products, whereas the same reaction carried out with pure triethyl phosphite yielded only the desired 2-(N-phthalylamino)-1-oxoalkanephosphonates. These compounds underwent rearrangement to the s
