The reactions of 2-chloro- 1,3,2-dioxaphorpholane ed various sodium saltsof amino acids to afford the penacoordinated rpirophosphoraLnes containing aminoacid were studied by NMR apectra techinques. The results diowed that naforal α-amino acids had greater ability than 5-aedo acids to form the penacoordinatedspecies, which is important in the biosynthesis and prebiotic synthesis of oligo-pcytides and proteins.
