- Intramolecular cyclization of 1,3-diamino-2-hydroxypropan-N,N,ń,ń-tetrakis(methylphosphonic acid) upon phosphonomethylation of 1,3-diaminopropan-2-ol
-
Phosphonomethylation of 1,3-diaminopropan-2-ol affords the mixture of 1,3-diamino-2-hydroxypropan-N,N,ń,ń-tetrakis(methylphosphonic acid) (1) with its cyclic ether, viz., [(6-[bis(phosphonomethyl)amino]methyl-2-hydroxy-2-oxido-1,4,2-oxazaphosphinan-4-yl)methyl]phosphonic acid (2), but not 1, as assumed earlier.
